Wheelbase to be 2290mm (90") minimum and 2693mm (106") maximum, wheel Track Width to be 2185mm maximum, Body Width to be 1500mm minimum and 1730 maximum, stiffening ribs included. Again we have three standards, depending on if you are Proto, Standard, or Hi-Rail. The short and simple answer is: Widening your rear track width gives you more understeer (more rear grip), narrowing your rear width gives you more oversteer (less rear grip). What has happened (as in many scales) is that with the track generally available in one physical gauge, you can use the same track gauge to represent different scales. The contour of the flange, the thickness of the very edge makes this really worthless. 7. In most scenarios, wheel track and axle track are the same length. A track width . While most U.S. railroads were designed by U.S. engineers, not British expatriates, a number of early lines were built to fit standard-gauge locomotives manufactured by English railroad pioneer George Stephenson. You also have the option to opt-out of these cookies. Use it as a rough check only. Assuming a 12.5 wide tire in DUMPs example and dividing wheel base by track width you get a range of 1.56-1.72. It has 2 rectangular slots on one side to "measure" wheel gauge. Hot Wheels cars are available in f. A short wheelbase vehicle is usually able to corner faster but may be less aerodynamic. Then you drive on the highway as if you were driving a semi-trailer. This website uses cookies to improve your experience while you navigate through the website. Switch point spread - detailed in the document. All of these were revised in February 2010. Long wheelbase cars are often better looking, too. None of the information is entered into the databases by ourselves. According to the Encyclopedia of American Business History and Biography, at the beginning of the Civil War, there were more than 20 different gauges ranging from 3 to 6 feet, although the 4-foot, eight-and-a-half inch was the most widely used. It's 1.125 for the other "G" scales. ), Covered Hopper lowering and Kadee body mount, HW Conversion: 2 to 3 axle - Napa Valley Wine Train, Fitting roller bearings to plug door box vignette, LGB's freight Trucks & Mods for Car Lowering, USAT Intermodal Car & Kadee 907 Centerset Couplers, Kadees for Bay & Extended Vision Cabooses, USA Trains American Series Woodside Reefer & Body Mount Kadee 789s, Aristo 1st Gen Floors & Kadee Body Mounts, Aristo Covered Hopper, Lowering & Kadee Install, AML Reefers with Kadees and AML coupler boxes, Aristo Flat & Gondola, Lowered, Weighted, Centerset Kadees, Aristo Fruit Growers Express RBNX Insulated Box Car, Aristo GP40 Problems - Smoking Motors & Debilitated Wheels, Aristo Revolution 15 Amp Base Station Implementation with PWC / Linear control, Aristo SD45 Weights & Railing Installation, Aristo Signal Bridge ART-7110 Electrical Nuances, Aristo Tank Car with Body Mounted Kadee 907s, Custom Kadee Coupler Boxes for Aristo Locos, Kadee #1 vs. G couplers - Metal Coupler Box, Kadees for USAT Bay & Extended Vision Cabooses, USAT SP Hydra-Cushion Boxcar & Kadee 830s, USAT Streamliners with Kadee 906 centerset couplers, Aristo Heavyweight Passenger Car & Body Mount Kadee 907s, LGB Modern Tank Car - Weighted, Lowered, Kadees, LGB Center Flow Hopper Car w/Kadee Couplers, USA Trains Modern Tank Cars & Body Mount Kadee Couplers, USA Trains 60 foot Box Car Body Mount Factory vs. Kadee Knuckle Couplers, LGB Modern 50 foot Box Car & Body Mount Kadee 907s, LGB's American Standard Gauge 1/29 Scale Trucks & Mods for Car Lowering, Aristo FA1/FB1 Lowered & Body Mount Kadee 907s, Upgrading Aristo-Craft Loco Motor Blocks from Sleeve to Ball Bearing, AML High-Cube Box Cars & Kadee Body Mounts, GP7/9 & body mount Kadees w/3d printed components, Aristo 50 ton 2 bay hopper car & body mount Kadees. Evaluating Average Car Width by Class 1. Unfortunately the official site has no English translation, here is a link to the applicable standard (a new one just for "garden trains": click here for NEM 311G. Mueller translated the 310 standard for me: click here for a translation of NEM 310, (note, I also need to also check out NEM 313). Honestly it's really not useful for these functions except to tell you if you are WAY out. Aristo gauge 0.097" NMRA standard S-3.3 0.100" G1MRA (Note target is 0.120"). Status Date. This is because it's difficult to make "proper" frogs in G scale, and flange-bearing frogs have their own problems. If it is not obvious, the back to back spacing is so under gauge it's lifting the wheel treads off the rail head. Easiest way to increase track is to . The cookie is used to store the user consent for the cookies in the category "Other. (.118"). It's 1.063" for 1:29 & 1:32. I've also checked out the Kadee coupler height gauge, since it has a wheel and track gauge incorporated. OK, so maybe all of this is boring so far, but there is some relevance here: the scale you use can affect the standards you follow. Vehicle dimensions with DOMINATOR tracks installed. Measure across the tires on one axle from the outside of the tread on one tire to the inside of the tread on the tire on the other side of the vehicle, using a tape measure. Never use the maximum. I think if you read between the lines here, EVERYTHING probably meets this standard, and the exceptions really take you back to the "wild west" of G scale. If you dont see your vehicle listed, please feel free to call or email. Where you see the wheel size written down such as . Please, don't use this gauge except to determine if a wheel has moved GROSSLY out of gauge. Obviously what has happened is to set a "target" properly, but "Grandfather in" the existing manufacturer's toy like switches. LGB solved this with flange beaing frogs, that is, the edge of the flange rides on the bottom of the flangeway around the frog. The moving assembly inside that actually causes a train to take a certain route is called the "points" and those rails are also called point rails. Some of the stability can be regained through widening the wheel track (distance between the tires on a given axle). I would file down the Aristo gauge to make it usable. How does wheelbase affect the stability of a car? The Fora platform includes forum software by XenForo, www.geocities.com/lakota_circle_dancer/swap1, VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Was wondering if an S10 4X4 would work, have a line on an 1988 model. The track width has to be determined first for determining the suspension hard points and geome. It gives you the the understanding of the critical relationships between these elements, has nice drawings, and explains how and why guardrails keep a wheel from hitting the point of the frog, how a wheel traverses a frog without dropping in, etc. Triple Driveway: 20x30 minimum. In the case of a three wheel vehicle (LB or LE) or a motor cycle with a side car (LD), the maximum width must not exceed 1,850 mm. Hotrodding is much more than just owning a hotrodIt is a state of mind! . Increasing track width lowers weight transfer, increasing handling. Best thing to do is carry a tape measure with you and measure everything that you see untill you come up with one that will work. The spacing between the wheels Standard values for track gauge follow from the scale being modeled as determined in step 2. It will increase the overall Track Width by 20 mm 2. Minimum width 10 feet, preferred 12 ft to allow car doors to open and step onto pavement. Answer (1 of 6): The number you are looking for is called the track width. The wheel "gauge" is just plain goofy. P-33. Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. Some cars might be wider at the front end than back end. I will focus on the back to back specification, and only in the Hi-Rail standards as the new standard has another improvement in it that makes a lot of sense: In the new approved 1/2015 S-4.2 "Standard" standard: click here for the 4.2 standard (Note that the large scale standards are on the last 2 pages), In the new approved 2/2010 S-4.3 (old "Hi-Rail") standard "wheels with deep flanges": click here for the 4.3 standard (Note that the large scale standards are on the last 2 pages). A switch is basically a construction that allows 2 or more tracks to combine to one, or vice versa. When I started this investigation, the Aristo-craft Track & Wheel gauge ART-11906 came on the market. However, you may visit "Cookie Settings" to provide a controlled consent. What crap this is, basically messing with the back to back makes your operation through turnouts worse, and this is the #1 cause of derailments. Here is the root web page for all of their standards: https://www.morop.eu/index.php/de/ so you have to stay in German to navigate to the standards pages, if you are in English, all you get is a page of apology for not translating them sheesh, how long does this take? This is the first combination gauge available, so I relate the Aristo gauge to the standards below to see if it could be a workable tool. We are reliant upon outside agencies These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. (Yes it is missing the levelling vials, they are held in with hot glue and always fall out, they are pretty worthless anyway except at a gross level). Is there a site or series of sites that give wheel base AND track width for various cars and trucks? The vast majority of any car's interior sits between the wheels, so a car with a long wheelbase will tend to have a more spacious interior . This measurement is the track width. Whats the difference between wheel base and track width? This means more grip. Check-In by 3:00 pm (no exceptions) Maximum length: 192 inches (16 feet) Maximum height: 85 inches. People may be concerned whether a tracked vehicle will fit in their garage or on their car hauling trailer. So, I will focus on 1:29 scale, standard gauge, used outdoors. So how does your rear track width affect oversteer and understeer? The standards that follow now refer to the NMRA's idea of 3 different classes of modeling: Proto & Fine Scales (where wheels & track are very close to exact scale) (NMRA standard S1.1), Standard (where wheels & track dimensions are somewhat "coarser" than exact scale - "standard modeling") (NMRA standard S1.2), Hi Rail (origin in the "high rail" of toy trains, our "Garden/Outdoor railroads" fit here in the NMRA's "mind") (NMRA standard S1.3). H-36. Using the More on this later, but it seems another political attempt to "grandfather in" deep flanges to keep the manufacturers "happy". C-38. In high performance vehicles a longer wheelbase is more stable at higher speeds. This also implies sloppier and narrower back to back spacing on wheel sets (another historical situation with Aristo and LGB). Likewise, the track gauge is one measurement only. unable to certify that a vehicle history is complete. An S-10, which is a somewhat popular swap, is about 54". There is also a note that says if you use flanges greater [thicker] than 0.076" you should reduce the back to back, but stay within the check gauge, and this is highly recommended. Rear track being wider than front track will make the car turn in better. How does wheelbase length affect handling? wheel base (the distance between the front and the rear wheels) has to be larger than 200 mm and the track width (the distance between two wheels on the same axle) has to be larger than 160 mm. Even then you should not use the huge, sloppy tolerances given. 3. It will stabilise the vehicle as the wider track widens the footprint on the road The Rules in Relation to Track Width - Which is affected by Wheel Offset Track width on Passenger Cars must not be increased by more than 26 mm Use it, it's only .002 deeper than the minimum spec, and you really do not want your flanges riding on the frog. USAT SD40-2 experiences, including Kadee centerset couplers, USAT 44 Tonner Experiences & Kadee Couplers, Bachmann / Soundtraxx "Thomas family" OEM decoder, http://www.g1mra.com/pdf/standard-dimensions-for-gauge1.pdf, back to back gauge is 1.575" +.019, -.005, or a minimum of 1.570" and a maximum of 1.594". Note also that what MOROP calls "large scale and garden railways" is not us. People may be concerned whether a tracked vehicle will fit in their garage or on their car hauling trailer. The standards are organized in sort of a top-down approach, so I start with the most basic and overall standards, and then go "down" in increasing level of detail. There are a wide variety of sedan sizes, from economy to full-size. Don't use it, use calipers to get to 0.106" or even less. Its therefore a smaller number than the cars full length, as measured from its front and rear end. Check a earlier Dodge Dakota outI believe it will be close. Never go to the maximum unless you want to use G1MRA standards, just make sure the wheels are plenty loose on the Minimum part of the gauge, and just start to "climb" over the Maximum part of the gauge. What is wheel base and track width? But different scales require different size and spacing of ties, and different rail "height", representing the different "weight" of the rail in the prototype which was sized to the weight of rolling stock and usage. Come join the discussion about restoration, builds, performance, modifications, classifieds, troubleshooting, maintenance, and more! Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The NMRA, the G1MRA, and MOROP (who administer the NEM standards). Expressed as a measurement from outside to outside, front and rear track will be 70mm. Length: 20', 21', 22' Capacity: 12,000 lbs; Width: 96", 102" Steel - Conventional or dual angle - 3/16" diamond or smooth decking - Fixed or removable tubular side rails - Removable blade side rails. I suggest if you have one of these, measure it and adjust it to match the tolerances you are working with (hopefully following a standard!). Height: 162 in. In real railroads, the angle of the frog is typically so slight that SOME portion of the wheel is always supported, or if not, the flange of the wheel will roll in the "flangeway" between the frog point and the wing rails. Well, as far as I can tell, there are only 3 groups recognized in the world that have standards applicable. so in most switches (except wyes and 3 way switches) one "path" is straight and one curved. accuracy of the information in our database cannot be guaranteed or verified, and we are According to SAE Track Width is the lateral distance between the center of the contact patch. Standard Vehicles. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. If the car has positive Ackermann, the amount would be reduced by increasing the track relative to the wheelbase (lines projected along the steering arms would intersect further to the rear). A forum community dedicated to hot rod owners and enthusiasts. This sucks. Wheel base is 117-118 in, Measured track width , center of tire to center of tire 60 in. Example: A wheel with an actual Diameter of 18" will have an overall diameter of around 19.5". This cookie is set by GDPR Cookie Consent plugin. It measures 8.7 feet wide, not including the mirrors. service for more information. The cookie is used to store the user consent for the cookies in the category "Performance". Larger front track width decreases this weight transfer. It also has 2 prongs to measure track gauge. Use standardard S1 to undedrstand definitions. 1. The cookies is used to store the user consent for the cookies in the category "Necessary". Regular road cars generally have wheels that are between 14 and 19 inches in diameter, with newer, more sporty, and luxury cars generally having the larger sizes. In my experience, using closer tolerances (similar to these new ones) combined with a better back to back setting on wheelsets, has VASTLY improved my ability to run more reliably through switches. If you want a simple answer, first, there is not one, but you can read my "conclusions" section below, it's my opinion. If you need to translate the .pdf files, click on the links on the Google-translated page. But the go/no go allows you some tolerance. Increasing the front more will lead to more oversteer which we already have a heaping helping of in our cars. So, naturally I looked for standards, and I have tried to make sense of the ones I have found. You CANNOT have sloppy specifications and loosen up the guard rails and wing rails and get smooth operating switches. Vehicle dimensions . The cookie is used to store the user consent for the cookies in the category "Analytics". Wondering if S10 frames would be ok. But the same minimum flangeway depth is just downright stupid. However, in the case of offset wheels, the two differ. Rack and pinion unit mounted in the cockpit of an Ariel Atom sports car chassis. Dimension D is the measurement from ground to center of hubs. These are identified below. ), Wheel back to back maximum (Aristo gauge perfect), Wheel back to back minimum (Aristo too wide/restrictive in all cases, the true allowable minimums are smaller), Flangeway width maximum (Aristo over spec) (at frog), 0.109" Aristo gauge 0.106" NMRA standard S-3.3 0.140" G1MRA (Note target is 0.120"), Flangeway width minimum (Aristo ?? I hope you are getting the message that all this stuff is inter-related, and once you loosen the tolerances in one area it has a ripple effect all through the system. Why does blood have to be infused in 4 hours? Another BIG change is that the Hi-Rail standards have been refined from being totally toy-like to something that will work better outside AND will allow long trains and better operation. Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use. This cookie is set by GDPR Cookie Consent plugin. . I use it's min/max feature to set my wheels. Track Check Gauge - distance from flange side of a guard rail to flange side of a frog, Wheel Check Gauge - distance from the back of a flange to the tread side of the other wheel, Span - distance between flange sides of guard and wing rails, Flangeway Width - distance between flange sides of wing rail and frog, Flange clearance - vertical distance from railhead to highest obstruction below it, Flange depth -actual depth of the flange on the wheel. The July 2009 standard tightened this up again. When measuring for the Actual Diameter, you will want to measure from the inside of the Barrel of the wheel (Shown by the Red Line in the above photo). Use the minimum part of the gauge to check the track, but if it's "tight" on the gauge, it could still be fine. The back of the wheel flange is limited in travel by the guard rails. Dave Goodsen recommends a flangeway width of 0.120" as a target. FOR FREIGHT CAR SERVICE - CARBON STEEL (M-107/M-208) AAR Type. Maximum tire width: 14 1/2 inches. I am not recommending the S-10, just pointing out the range of frame clips. To make this clear, once you have sloppy back to back tolerances, you have to increase the flangeway widths so much the wing rails and closure rails cannot support the wheel tread through the frog, and the wheel drops into the frog with a bump. Answer (1 of 3): While cornering and braking weight transfer takes place diagonally that is from rear right to front left or vice versa. In the case of a two wheel vehicle (LA or LC), the maximum width must not exceed 1,000 mm. On average, you will find that standard cars and trucks range from 10-feet to 18-feet in length. Why is the length of the wheel base irrelevant? when the current NASG steel wheel-and-track gauge was first manufactured, the company that did the actual work, printed the text on the . Turn the steering wheel so the front wheels point straight ahead. It is easy though for people that are not as anal as me ha ha!. STND . and im currently 100 miles away . 43.18 mm Aristo gauge 41.5 - 41.63 NMRA standard S-3.2 (Note, this is for I gauge, the NMRA does not specify this for G gauge in the S-3.3 standard, I suspect this would be relaxed in the S-3.3 if it was specified), Here is the link to see the standards:http://www.nmra.org/sites/default/files/standards/sandrp/pdf/s-3.2_2010.05.08.pdf http://www.g1mra.com/pdf/standard-dimensions-for-gauge1.pdf. RACK AND PINION. Another cheap sell out to grandfather in poor wheel standards from manufacturers. Answer (1 of 2): There is no straight forward formula for this. spec) (at frog), ?? Size An emergency vehicle may exceed otherwise applicable vehicle size limits up to the following maximum values: Width: 102 in. Due to the inherent nature of large scale trains, the wheel and track standards for Standard (Sx.2) andDeep Flange (Sx.3) are identical except in terms of flange width and depth, thus the track H depth also is changed. Aristo's "Plastic [In]compatible" ELECTRALUBE Legacy! The length of the wheel base will always be decided by its vehicle use. This comes out to about 1.587". There's also some variation in the gauges I have measured. This is simply because theres more time between the front and rear wheels hitting any bumps, so the car is less likely to become unsettled. Before diving into numbers, a small explanation of my focus, since there are a lot of different SCALES that use "G" gauge track, 45 mm. There are no industry standard wheelbase sizes, but a typical city car might have a wheelbase of 2,430mm, while a family hatchback could have a 2,700mm wheelbase, and a large SUV's might be 2,980mm. Front track wider than the rear. Most of the unibody cars got wider because of the disc brake hats. This cookie is set by GDPR Cookie Consent plugin. The flange depth of under 2mm is nuts, run 2 to just short of 3 mm flange depth, too many of our locos do not have adequate suspensions. For example, the 2004 standard has a guard rail flangeway width from 0.106" to as large as 0.131, and a flangeway depth of 3 mm. Picture kids removing their bicycle from the garage and allow enough space between vehicles to avoid a scratched car. (1) U.S. track gauge based on UK track gauge. OK, now we are on to the more detailed standards. Unfortunately, the February 2010 standards go backwards, with a specification of 0.115, +0.002 and minus 0.023". All we can do as a designer is to take reference from similar vehicles and then iterate the values on some software like Lotus Shark etc. For a better experience, please enable JavaScript in your browser before proceeding. Dimension C is the measurement from outside of grease cap to outside of grease cap. Rear wheels closer helps in attaining traction. File it down to meet the spec. Also the flange depth is nuts for outdoor use. (2) UK railway track gauge based on width of earlier tramways used to haul coal. Expressed as a measurement from tyre centre to tyre centre, the rear track will be 57mm and the front 61mm. This is very popular in the areas outside of the US and England. The first section will list wheelbase, front track and rear track of vehicles in inches, so that those interested in frame swaps or clip swaps can find the correct donor vehicle. In the prototype, i.e. A cars wheelbase is the distance between the centres of the front and rear wheels. I set everything to an exact value, rather than see if I am in range. We are happy to help you find whatever dimensions you need. Interestingly, car sizes have increased and decreased over the years due to consumer . Galvanized sub frame and wheel lift components Deck. Trolley Wheel Width (W) 1/16" (+/-5%) 1.6 mm (+/-5%) Trolley Wheel Diameter (D) 1/8" (+/-5%) . A 4mm difference. This standard allows for really deep flanges. CLICK HERE to view NMRA approved standard S-1. Because of the effect the wheelbase has on the weight distribution of the vehicle, wheelbase dimensions are very important to the balance and steering. (So technically, there are no such things as "MOROP standards", only NEM standards.). STND 1956. . Basically with the exceptions and sloppy and asymmetrical tolerances everyone is "grandfathered in" with no changes in production needed. I'm disappointed by this, so my opinion is to follow the target values for the "standard" standards, not the proto/fine and not the deep flange standards. Over the past few years we have had quite a few inquiries about track truck dimensions. The average width of a midsize vehicle is about 6 to 6.5 feet long. Also, "G" gauge track is appropriate for narrow gauge modeling, but the resultant scale for the track to represent 3 foot narrow gauge yields a rolling stock scale of 1:20.3. NEM is the name of the standard, and MOROP is the group that works on the standards. When a disturbance (bump, wind gust) gives the front wheel an accidental steer input, a long wheelbase reduces the degree to which this also steers the rear wheel. They function like the guard rails in controlling the wheels as they move through the frog. The Chevy Spark is currently the narrowest on the road, measuring 5.2 feet wide. It even specifies height of hook and loop (0.75"). The length of the vehicle on nearly all vehicles is irrelevant because it it not extreme, until you get into the sphere of the stretched limo. Thanks for the reply and the web site has a lot of good info. Also, indoor modelers can utilize standards closer to the actual prototype dimensions. Answer: Hot Wheels and Matchbox cars and trucks vary considerably in size, and there is no standard dimension. Mine was not exact and needed a couple of whacks with a file to be right. There are also some other exceptions on this page where back to back can be decreased to 1.542" and the wing rail flangeway increased to 0.131". Probably a mistake, but no one fixed it. Exclusive of rear view mirrors, turn signal lamps, handholds for cab entry/egress, splash and spray suppressant devices, load induced tire bulge, a fixed step up to 3 inches deep. Due to the inherent nature of large scale trains, the wheel and track standards for "Standard" (Sx.2) and"Deep Flange" (Sx.3) are identical except in terms of flange width and depth, thus the track H depth also is changed. I know this question has been asked before, I just can't find the answer, so here goes. Same car, different result dependant upon the way it's measured. Even an A or G body GM is about 58" to 58.5". It's not even worth giving a measurement here since it means nothing. The same is true of stability. Rack and pinion steering mechanism: 1 Steering wheel; 2 Steering column; 3 Rack and pinion; 4 Tie rod; 5 Kingpin. By clicking Accept All, you consent to the use of ALL the cookies.

Please note that while there are usually 3 sets of standards for each category, not all are applicable to 1:29 scale outdoors, so I list all the applicable standards, both approved and proposed. Thanks all. Interestingly, the 4-foot, eight-and-a-half inch width has not always been the standard in the U.S. Cars with long wheelbases tend to have better ride quality than those with short wheelbases. Dimension A is the measurement from center of track to center of track. M-33. The track width is hard to deal with since wheel offset makes such a difference. Wheel track or track width is the distance between the centerline of two wheels on the same axle. The cookie is set by GDPR cookie consent to record the user consent for the cookies in the category "Functional". (Yuck). Ford cars over the years used the same rear end width, wheel to wheel, and advertised track width varied from -1 inch to +2 inches. A standard 40-foot box car should weigh 5.75 ounces (2oz + (7.5" x 0.5oz)), or 163 grams for a 19.1cm car. Note: for the flangeways on the stock rails (the outer 2 rails of the switch) the spec is 2.69mm (0.106), 3.04 mm (0.120") (approx) Aristo gauge for frog 3.00 mm minimum (0.118"), no max specified, NMRA standard S-3.3 NOT SPECIFIED by G1MRA, Switchpoint spread maximum (??? This is the distance from the center of one wheel setting on the ground to the center of the opposite wheel on the ground. This is always referred to in inches, and as the name suggests is the diameter of the wheel - not the tyre and wheel together. J-33. Standard Steel currently manufactures a variety of types and sizes . The purpose of them is to keep the wheels on the proper course as the tracks "cross" each other at the frog. Aluminum - Conventional or dual angle - Extruded 6061-T6 decking The final Track Width measurement uses the average of multiple independent measurements in order to minimize errors associated with small steer angles. (This is the setting I use). I can get wheelbase pretty often but hard as hell to get track width. So let's try to get an overview of how these are organized. Front tire wider than rear also helps in steering (decr. I use the 5/2010 "Standard" standard - S3.2 - if you read this, you see that other than minimum flange clearance, this standard is the same as the 1/2006 Proto 20.3 standard - S-3.1 Now we are getting somewhere! In automobiles (and other wheeled vehicles which have two wheels on an axle ), the axle track is the distance between the hub flanges on an axle. The rail used for the track Wheelset dimensions are determined by the track gauge and the three items above and provide: 4. Click here to see the G1MRA specification. ie, a wheel of 8 inch wide with an offset of et 15 will stick out of the arch 20mm more than a set with an et of 35. Wheel Width Measuring the Wheel width is similar to measuring the Diameter. In the hobby, we represent this by saying:"code xxx" where xxx is height in thousandths of an inch, for example code 332 is 0.332 inches tall. 2 Car Driveway: 20x20 minimum, 20x24 is preferred. I'll only include the "WHEELS AXLES AND TRACK, STANDARD GAUGE 1", as the fine scale standards are not applicable here. We have been working to compile an extensive chart to detail this information. Once again thanks. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Easiest way to increase track is to fit wheels with a calculated offset/width . (avoid calling it the curved main rail, since there are curved turnouts also, and not all turnouts appear to have a curve) On the 2 main rails, there are 2 smaller pieces of rail called "guard rails". I'm presently trying to find a donor truck frame to put under a 1941 Dodge 1/2 ton PU. It will only tell you if the wheelset is grossly out of gauge, and will set different back-to-back measurements based on flange thickness/contour. We also use third-party cookies that help us analyze and understand how you use this website. Thankfully H.J. FIG 6. It will fill up the guards making the appearance "more tough" 3. Conversely, as the wheel base length shrinks, stability is lost, but you gain in maneuverability. [1] Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Note: if you really want to learn and understand, then read all of this. A standard width measurement on a car would be measured across the rooftop and go from the front driver side over to the same point on the front passenger side of the vehicle. 7 Whats the difference between wheel base and track width? Front and rear track the same. D. 40" Tapes +14-0. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Some might confuse it with axle track, which is the distance between the hub flanges on an axle. 6.5.2.2. It does not store any personal data. wheel base (the distance between the front and the rear wheels) has to be larger than 200 mm and the track width (the distance between two wheels on the same axle) has to be larger than 160 mm. Wheelset designs for less common gauges can be found by adjusting the values given. . For most high volume production, this is usually mounted on the other side of this panel. Originally I was very "hot" on this idea, but since you can buy a set of digital vernier calipers for about $20 at Harbor Freight, this is more of an exercise in convenience. 43" Tapes . The flangeway depth is minimum 0.118 (3 mm). (Yuck). Choose the make of the car you are interested in and find out about its Wheelbase specifications. This is a favorite standard for people in England, and many narrow gauge modelers here in the US. public databases. Necessary cookies are absolutely essential for the website to function properly. For those of us in "G" scale outdoors, the most recent changes is that Large Scale is now also in the STANDARD scale category. (Yes, I know that 1:29 is not "purely correct" for the scale/gauge combination.). How does track width affect the steering geometry? There are significant compromises involved in using this standard, both in appearance and operation. Sedans. The standard notes that the flange depth of 3mm is to accomodate deep flanges and results in flange-bearing frogs. Also there is an error in the standard. Dimension B is the measurement from outside of track to outside of track. flange thickness is 0.059" + 0.002" -0.018. max depth of the flange is 0.066 (1.68 mm), back to back gauge is 1.575" +.019, -.015, or a minimum of 1.560" and a maximum of 1.594", stick with the NMRA "standard" standards, 3.2 and 4.2. S-10 rears are about 57 1/2 wheel to wheel, like most Fords of the 50s, 60s, and these all fit well from the 30s cars right on up. I model large scale standard gauge. The outer 2 rails of the switch are called the "main rails", and you can call one the "straight" or "through" main rail, and the other the divergent rail. The early 2009 standard has a specification of 0.104", with a tolerance of - 0.002 and + 0.007 ( 0.102 to 0.11 ) much more reasonable in my opinion, and keeps the 3mm minimum flange depth. These cookies ensure basic functionalities and security features of the website, anonymously. From a little G. Please realize that there are many different scales that use "G" or #1 GAUGE track, 45mm. Why do you have to swim between the flags? Ackermann steering geometry would be affected. K-36. It is my opinion that the 1:20.3 people here in the US are much more concerned with scale and gauge than the 1:29 modelers. This cookie is set by GDPR Cookie Consent plugin. This is the entry point for standards. These are called "wing rails". The standards approved are still sloppy and have too much slop in them to grandfather older equipment and poorly manufactured equipment. 8 How does wheelbase affect the stability of a car? The stock track width is about 56" according to the factory shop manual. The 'Overall Width' of an L-Group vehicle must be as follows : 6.5.2.1. The length of a car is measured from the . I don't know anyone who can do this outdoors. Anyonw know what the standard wheel track width is for the TL-01 chassis (tyre centre line to tyre centre line when viewed from front) Im trying to figure out what wheel offsets i need for my Bowler project, using a standard TL-01 chassis (no LA or B conversion!!) The part where the tracks "cross" each other is called the "frog". This needs further research, but this sloppy spec is the #1 cause of wheel flanges hitting the frog. Over the past few years we have had quite a few inquiries about track truck dimensions. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. In my opinion, the new standards are good news, the Hi-Rail standards have been revised to much more reasonable specifications. I think most people (and manufacturers) will use the old "Hi-Rail" standard 2/2010 "Deep Flanges" standard - S-3.3 - for deep flanges. It's supported by facts, but it's my opinion. This means there has to be some "reasonable" route to make Aristo, USAT, Bachmann, and other 1:29 stuff conform to the standard, also track, especially turnouts. The shorter the lever the more the rear wheel is steered and vice versa. someone help me out on this one). Ford cars over the years used the same rear end width, wheel to wheel, and advertised track width varied from -1 inch to +2 inches. CLICK HERE for the main NMRA standards page. Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. . Ground clearance: 4+ inches. If you want outside of tread to out side tread you would have to add a tire width. This works, as long as you have huge flanges, and ALL the SAME depth. Use Google Translate to translate the page with the links, but then open the native French web page in another window/tab to open the standards and look at the .pdf files. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Track gauge maximum (Aristo over all specifications, allows too wide track gauge in all cases of all known standards), (Note that NMRA Approved Standard S-1.3 did not specify max or min gauge, but gauge was specified as 1.772" absolute) (Note here and in other measurements that the G1MRA original standard specified a target value with no tolerance +-), Track gauge minimum (Aristo gauge under specification, "too tight", would "fail" some track that meets other minimum specs), (Note that NMRA Approved Standard S-1.3 did not specify max or min gauge, but gauge was specified as 1.772" absolute, therefore using this part of the gauge with no tolerance will meet the existing Hi-Rail gauge standard. These cookies will be stored in your browser only with your consent. for our data, which you resolve to access at your own risk. If you only widen at one end, then that end will gain traction and the other will not which changes the handling balance. ), I strongly suggest you read this specification (linked below). Recommendation: file the Aristo gauge down in both places to meet the standard you want, I would suggest the Hi-Rail ones. This is my recommendation since once set they seem to be good forever. J-36. For example, "G" gauge track is appropriate for 1:32 standard gauge modeling. You can make it up some with additional tread width in the back, or a stiffer rear swaybar, or spacers. Rear track being wider than front track will make the car turn in better. Vehhistory.com provides you with access to material and information from B-38. You get the text, but not the illustrations. Being an engineer, I am constantly investigating the factors that will make my railroad run the most reliably. This is what I want to avoid: (the combination of back to back and the flangeways actually has ripped wheelsets apart in some cases!) 2.69 to 3.33 (0.106" - 0.131") NMRA standard S-3.3 (only for flangeways on wing rails (frog), and only if for "G" only, designed to accomodate older G scale, and wheelsets with a back-to-back of 1.542", and you can no longer run #1 scale wheelsets). Some are prototype standard gauge (1:32) and some are narrow gauge and the scales are quite varied. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Looking at the frog, you will see space where the wheels are not supported as they roll through. Note: The MOROP standards are not available in English. JavaScript is disabled. Ideally, the cars are built to a 1/64th scale, however after owning many cars over the years, you start to see that this is more of a rough guideline. What did Britain do when colonists were taxed? S3.2 says: Again we have 3 classifications, and again, the Standard and Hi-Rail standards have been updated in February 2010. I want a "workable" set of 1:29 scale standards, that improve the quality of operation, and have some chance of being used on current production 1:29 rolling stock. New, and gives the coupler height and tolerance for various scales. It basically measures some range of the edges of the flanges, which is a terrible way to measure either back to back or gauge. The The proper flange thickness also allows you to have nice reasonable flangeway widths, so besides looking toylike, it allows the wing rails and closure rails to work properly around the frog, supporting the wheel, so the wheel does not fall into the frog. Dimensions will be listed left to right as wb/ft/rt followed by the year, make and model of the vehicle. I know that there is check gauge which tries to combine wheel gauge and back to back, but the width of our wheel treads is so wide, that all you need is a proper back to back and a flange of the proper thickness and everything works out. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. It is way too wide. Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use. Maximum width: 84 inches, including mirrors. Why are you allowed to use the coarse adjustment when you focus the low power objective lens? It is within specifications, but I again would use it only for a rough check. But opting out of some of these cookies may affect your browsing experience. Most of the unibody cars got wider because of the disc brake hats. 1:1 scale, this resulted in different gauges. In the case of an axle with dual wheels, the centerline of the . Hoo boy, that's an endless debate! This is for toys. The G1MRA standard can be followed and everything will be fine, except the flange depth. The tolerances make sense. Analytical cookies are used to understand how visitors interact with the website. Equal. For instance: 86.0, 50.6, 50.3 -- 1952 Morris Minor. Before we go there, some explanation is necessary. the flange depth is max is 0.079 (more sense than the NMRA 0.068) although they state you can use 1.5mm 0.059 if you want for sprung/equalized trucks. True. (what sense does this make with a 3 mm MINIMUM flangeway? It is only ONE page! This is the place that most people would "start" if they came from other scales and were in the US. The frog actually has several components, the point where the 2 rails in the middle come together, called the frog point (sometimes called the "frog heel"), and the 2 guard rails that sort of wrap around the point. By calculating from the other specs, the flangeway width (on the stock rails) should be .097 min, .112 max for the guardrail width (on stock rails), but I would stick to 0.106 maximum. Where is the wheel base measured from? DIMENSIONS AND TOLERANCES - ALL ENTRIES IN INCHES, EXCEPT TAPES. It defines the structure of the standards, and defines the terms: If you are not an expert in track (and even if you think you are! Which is better? Please refer to our terms of Basic vehicle dynamics: the wider the track, the lower the amount of weight transfer. 1.793" NMRA Proposed Standard S-1.2 (Standard), 1.793" NMRA Proposed Standard S-1.3 (Hi-Rail), 1.762" Kadee track gauge (one measurement only on this gauge), 1.765" Kadee track gauge (one measurement only on this gauge), NEM 310 no minimum specified (targes is 1.772"), 1.755" Kadee gauge (Note: there are 2 notches, this is the measurement of the notches, when used to set an old Aristo "split axle" wheelset, it set the back to back at, 1.582" S-4.2 standard (standard 1:20.3 ) (Note target is 1.580"), 1.574" S-4.3 standard (Hi-Rail) (Note target is 1.576"), 1.574" S-4.2 standard (Standard LS) (Note target is 1.576"), 1.591" Kadee gauge (Note: there are 2 notches, this is the measurement of the notches, when used to set an old Aristo "split axle" wheelset, it set the back to back at 1.587", EXTREMELY dependent on flange contour), 1.578" S-4.3 standard (Hi-Rail) (Note target is 1.576"), 1.578" S-4.2 standard (Standard LS) (Note target is 1.576"), 1.574" G1MRA Standard (Note target is 1.574"), 1.567" S-4.2 standard (Standard 1:20.3) (Note target is 1.580"). Some of the stuff I have done has fallen around a 1.6 wheelbase to track ratio which is about in the middle of DUMPs range. Passenger Wheels. 41" Tapes +14-0. Axle track. What are annual and biennial types of plants? Don't use it for these functions. Those standards are for the ride-on scales. Turnouts are the #1 cause of derailments in model train layouts. 2mm deep flanges are tough enough, don't try 1.68mm. The widest title belongs to the Ram 3500 with dually rear wheels. Single Driveway: 20x10 minimum. Since most of the available standard gauge rolling stock is available in 1:29 scale, I will focus there. Axle and wheel track are commonly measured in millimetres or inches. These cookies track visitors across websites and collect information to provide customized ads. FIG 4.
