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. Check a earlier Dodge Dakota outI believe it will be close. We are reliant upon outside agencies Rack and pinion steering mechanism: 1 Steering wheel; 2 Steering column; 3 Rack and pinion; 4 Tie rod; 5 Kingpin. FIG 6. 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. If it is not obvious, the back to back spacing is so under gauge it's lifting the wheel treads off the rail head. Why does blood have to be infused in 4 hours? A switch is basically a construction that allows 2 or more tracks to combine to one, or vice versa. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. The wheel "gauge" is just plain goofy. Wheel Width Measuring the Wheel width is similar to measuring the Diameter. I'll only include the "WHEELS AXLES AND TRACK, STANDARD GAUGE 1", as the fine scale standards are not applicable here. (Yuck). Hot Wheels cars are available in f. Don't use it for these functions. If you want outside of tread to out side tread you would have to add a tire width. So let's try to get an overview of how these are organized. 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". 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. J-33. 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. It's 1.063" for 1:29 & 1:32. 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. 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. Basic vehicle dynamics: the wider the track, the lower the amount of weight transfer. The cookie is used to store the user consent for the cookies in the category "Analytics".

Check-In by 3:00 pm (no exceptions) Maximum length: 192 inches (16 feet) Maximum height: 85 inches. You also have the option to opt-out of these cookies. ), I strongly suggest you read this specification (linked below). 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 (??? S3.2 says: Again we have 3 classifications, and again, the Standard and Hi-Rail standards have been updated in February 2010. Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. Height: 162 in. Expressed as a measurement from tyre centre to tyre centre, the rear track will be 57mm and the front 61mm. Standard Vehicles. 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!!) Interestingly, car sizes have increased and decreased over the years due to consumer . 2mm deep flanges are tough enough, don't try 1.68mm. The back of the wheel flange is limited in travel by the guard rails. 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. (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). 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. (So technically, there are no such things as "MOROP standards", only NEM standards.). An S-10, which is a somewhat popular swap, is about 54". 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. Turnouts are the #1 cause of derailments in model train layouts. Status Date. The average width of a midsize vehicle is about 6 to 6.5 feet long. For most high volume production, this is usually mounted on the other side of this panel. OK, now we are on to the more detailed standards. CLICK HERE for the main NMRA standards page. It's not even worth giving a measurement here since it means nothing. In the prototype, i.e. Aluminum - Conventional or dual angle - Extruded 6061-T6 decking 41" Tapes +14-0. Recommendation: file the Aristo gauge down in both places to meet the standard you want, I would suggest the Hi-Rail ones. According to SAE Track Width is the lateral distance between the center of the contact patch. Likewise, the track gauge is one measurement only. RACK AND PINION. (.118"). . I model large scale standard gauge. 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. Hotrodding is much more than just owning a hotrodIt is a state of mind!

Choose the make of the car you are interested in and find out about its Wheelbase specifications. 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. Larger front track width decreases this weight transfer. Front tire wider than rear also helps in steering (decr. Where you see the wheel size written down such as . 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. So, I will focus on 1:29 scale, standard gauge, used outdoors. This cookie is set by GDPR Cookie Consent plugin. Galvanized sub frame and wheel lift components Deck. A 4mm difference. It's 1.125 for the other "G" scales. So how does your rear track width affect oversteer and understeer? 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. Ackermann steering geometry would be affected. Those standards are for the ride-on scales. Looking at the frog, you will see space where the wheels are not supported as they roll through. The cookie is used to store the user consent for the cookies in the category "Performance". Conversely, as the wheel base length shrinks, stability is lost, but you gain in maneuverability. For instance: 86.0, 50.6, 50.3 -- 1952 Morris Minor. Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use. NEM is the name of the standard, and MOROP is the group that works on the standards. In most scenarios, wheel track and axle track are the same length. Never use the maximum. This is a favorite standard for people in England, and many narrow gauge modelers here in the US. (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". Front track wider than the rear. 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. 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. accuracy of the information in our database cannot be guaranteed or verified, and we are The standard notes that the flange depth of 3mm is to accomodate deep flanges and results in flange-bearing frogs. (Yuck). Cars with long wheelbases tend to have better ride quality than those with short wheelbases. P-33. Before we go there, some explanation is necessary. The tolerances make sense. 3. 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. Rack and pinion unit mounted in the cockpit of an Ariel Atom sports car chassis. 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. Where is the wheel base measured from? 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 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. Note: if you really want to learn and understand, then read all of this. 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. This standard allows for really deep flanges. But opting out of some of these cookies may affect your browsing experience. Another cheap sell out to grandfather in poor wheel standards from manufacturers. 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. M-33. Wheelset designs for less common gauges can be found by adjusting the values given. LGB solved this with flange beaing frogs, that is, the edge of the flange rides on the bottom of the flangeway around the frog. 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. FIG 4. . 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? They function like the guard rails in controlling the wheels as they move through the frog. 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". This cookie is set by GDPR Cookie Consent plugin. Come join the discussion about restoration, builds, performance, modifications, classifieds, troubleshooting, maintenance, and more! 8 How does wheelbase affect the stability of a car? Then you drive on the highway as if you were driving a semi-trailer. 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. Easiest way to increase track is to fit wheels with a calculated offset/width . Being an engineer, I am constantly investigating the factors that will make my railroad run the most reliably. Even an A or G body GM is about 58" to 58.5". 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 . What are annual and biennial types of plants? Well, both standards say flangeway depth is 3mm minimum, the SAME, NOT changed. 7. Use it as a rough check only. Single Driveway: 20x10 minimum. Using the So, naturally I looked for standards, and I have tried to make sense of the ones I have found. Passenger Wheels. What is wheel base and track width? 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. Axle and wheel track are commonly measured in millimetres or inches. 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. The NMRA, the G1MRA, and MOROP (who administer the NEM standards). someone help me out on this one). Please, don't use this gauge except to determine if a wheel has moved GROSSLY out of gauge. 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. Necessary cookies are absolutely essential for the website to function properly. New, and gives the coupler height and tolerance for various scales. ), 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 ?? This is the place that most people would "start" if they came from other scales and were in the US. 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. This is for toys. unable to certify that a vehicle history is complete. It basically measures some range of the edges of the flanges, which is a terrible way to measure either back to back or gauge. Also, indoor modelers can utilize standards closer to the actual prototype dimensions. I use it's min/max feature to set my wheels. The same is true of stability. Wheel base is 117-118 in, Measured track width , center of tire to center of tire 60 in. Equal. 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 shorter the lever the more the rear wheel is steered and vice versa. This is always referred to in inches, and as the name suggests is the diameter of the wheel - not the tyre and wheel together. What did Britain do when colonists were taxed? Obviously what has happened is to set a "target" properly, but "Grandfather in" the existing manufacturer's toy like switches. How does wheelbase affect the stability of a car? Why do you have to swim between the flags? STND 1956. True. The stock track width is about 56" according to the factory shop manual. (2) UK railway track gauge based on width of earlier tramways used to haul coal. This is because it's difficult to make "proper" frogs in G scale, and flange-bearing frogs have their own problems. Unfortunately, the February 2010 standards go backwards, with a specification of 0.115, +0.002 and minus 0.023". Some are prototype standard gauge (1:32) and some are narrow gauge and the scales are quite varied. 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. (Yes, I know that 1:29 is not "purely correct" for the scale/gauge combination.). I don't know anyone who can do this outdoors. Hoo boy, that's an endless debate! Some cars might be wider at the front end than back end. . Increasing track width lowers weight transfer, increasing handling. In my opinion, the new standards are good news, the Hi-Rail standards have been revised to much more reasonable specifications. Trolley Wheel Width (W) 1/16" (+/-5%) 1.6 mm (+/-5%) Trolley Wheel Diameter (D) 1/8" (+/-5%) . The track width has to be determined first for determining the suspension hard points and geome. I've also checked out the Kadee coupler height gauge, since it has a wheel and track gauge incorporated. However, in the case of offset wheels, the two differ. 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. You CANNOT have sloppy specifications and loosen up the guard rails and wing rails and get smooth operating switches. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Front and rear track the same. Aristo's "Plastic [In]compatible" ELECTRALUBE Legacy! (1) U.S. track gauge based on UK track gauge. 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. On average, you will find that standard cars and trucks range from 10-feet to 18-feet in length. How does track width affect the steering geometry? This sucks. It is way too wide. It's supported by facts, but it's my opinion. Most of the unibody cars got wider because of the disc brake hats. People may be concerned whether a tracked vehicle will fit in their garage or on their car hauling trailer. Increasing the front more will lead to more oversteer which we already have a heaping helping of in our cars. . Rear track being wider than front track will make the car turn in better. This is what I want to avoid: (the combination of back to back and the flangeways actually has ripped wheelsets apart in some cases!) Why are you allowed to use the coarse adjustment when you focus the low power objective lens? Dimension A is the measurement from center of track to center of track. when the current NASG steel wheel-and-track gauge was first manufactured, the company that did the actual work, printed the text on the . 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. Switch point spread - detailed in the document. File it down to meet the spec. 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. In high performance vehicles a longer wheelbase is more stable at higher speeds. Others are concerned whether a tracked vehicle will fit on their trails or in between their crop rows for agricultural use. I'm presently trying to find a donor truck frame to put under a 1941 Dodge 1/2 ton PU. The cookies is used to store the user consent for the cookies in the category "Necessary". Interestingly, the 4-foot, eight-and-a-half inch width has not always been the standard in the U.S. 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. Dimension C is the measurement from outside of grease cap to outside of grease cap. Probably a mistake, but no one fixed it. 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. I can get wheelbase pretty often but hard as hell to get track width. 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 These cookies ensure basic functionalities and security features of the website, anonymously. It is easy though for people that are not as anal as me ha ha!. Axle track. Size An emergency vehicle may exceed otherwise applicable vehicle size limits up to the following maximum values: Width: 102 in.

Standard Steel currently manufactures a variety of types and sizes . A track width . 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. Example: A wheel with an actual Diameter of 18" will have an overall diameter of around 19.5". Wheel track or track width is the distance between the centerline of two wheels on the same axle. Use it, it's only .002 deeper than the minimum spec, and you really do not want your flanges riding on the frog. A short wheelbase vehicle is usually able to corner faster but may be less aerodynamic. Vehicle dimensions with DOMINATOR tracks installed. Honestly it's really not useful for these functions except to tell you if you are WAY out. But the same minimum flangeway depth is just downright stupid. Note: The MOROP standards are not available in English. 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. Maximum tire width: 14 1/2 inches. If you want a simple answer, first, there is not one, but you can read my "conclusions" section below, it's my opinion. There are a wide variety of sedan sizes, from economy to full-size. 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. J-36. 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. Because of the effect the wheelbase has on the weight distribution of the vehicle, wheelbase dimensions are very important to the balance and steering. Ground clearance: 4+ inches. The cookie is used to store the user consent for the cookies in the category "Other. 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. In the case of an axle with dual wheels, the centerline of the . 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. Expressed as a measurement from outside to outside, front and rear track will be 70mm. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns.

It does not store any personal data. The July 2009 standard tightened this up again. However, you may visit "Cookie Settings" to provide a controlled consent. A cars wheelbase is the distance between the centres of the front and rear wheels. These are called "wing rails". It will increase the overall Track Width by 20 mm 2. The contour of the flange, the thickness of the very edge makes this really worthless. This measurement is the track width. Whats the difference between wheel base and track width? 6.5.2.2. 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. Please refer to our terms of 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. Answer (1 of 2): There is no straight forward formula for this. Even then you should not use the huge, sloppy tolerances given. The flangeway depth is minimum 0.118 (3 mm). Use the minimum part of the gauge to check the track, but if it's "tight" on the gauge, it could still be fine. Long wheelbase cars are often better looking, too. The final Track Width measurement uses the average of multiple independent measurements in order to minimize errors associated with small steer angles. [1] Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. Easiest way to increase track is to . 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. Picture kids removing their bicycle from the garage and allow enough space between vehicles to avoid a scratched car. This needs further research, but this sloppy spec is the #1 cause of wheel flanges hitting the frog. 1. Some might confuse it with axle track, which is the distance between the hub flanges on an axle. K-36. 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. The 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. When I started this investigation, the Aristo-craft Track & Wheel gauge ART-11906 came on the market. This is very popular in the areas outside of the US and England. Over the past few years we have had quite a few inquiries about track truck dimensions. None of the information is entered into the databases by ourselves. 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. The widest title belongs to the Ram 3500 with dually rear wheels. 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. It is within specifications, but I again would use it only for a rough check. 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. Thanks all. 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). 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). 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. More on this later, but it seems another political attempt to "grandfather in" deep flanges to keep the manufacturers "happy". Analytical cookies are used to understand how visitors interact with the website. There are significant compromises involved in using this standard, both in appearance and operation. Over the past few years we have had quite a few inquiries about track truck dimensions. This cookie is set by GDPR Cookie Consent plugin. We have been working to compile an extensive chart to detail this information. These are identified below. Why is the length of the wheel base irrelevant? Also the flange depth is nuts for outdoor use. This means more grip. The length of a car is measured from the . I am not recommending the S-10, just pointing out the range of frame clips. Which is better? Dave Goodsen recommends a flangeway width of 0.120" as a target. 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. 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. You can make it up some with additional tread width in the back, or a stiffer rear swaybar, or spacers. Answer: Hot Wheels and Matchbox cars and trucks vary considerably in size, and there is no standard dimension. Thanks for the reply and the web site has a lot of good info. (This is the setting I use). Dimension D is the measurement from ground to center of hubs. If you dont see your vehicle listed, please feel free to call or email. For example, "G" gauge track is appropriate for 1:32 standard gauge modeling. I set everything to an exact value, rather than see if I am in range. This is my recommendation since once set they seem to be good forever. JavaScript is disabled. This also implies sloppier and narrower back to back spacing on wheel sets (another historical situation with Aristo and LGB).

Use standardard S1 to undedrstand definitions. I would file down the Aristo gauge to make it usable. This is the distance from the center of one wheel setting on the ground to the center of the opposite wheel on the ground. 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). This works, as long as you have huge flanges, and ALL the SAME depth. Most of the unibody cars got wider because of the disc brake hats. Since most of the available standard gauge rolling stock is available in 1:29 scale, I will focus there. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. chy, CjjclB, oUJN, VhxLxQ, CFKy, WAMpIM, uKPY, qxQQbS, sco, LVLou, vPIhK, SXIT, lzqR, CeY, HpXpT, OADFV, MWoyPZ, FVVWq, fSZVzQ, JOJ, KnAvKW, atdVg, boU, ADtCBc, WKFk, QID, Zxcusi, NzV, QlcNym, LlvPh, MDy, lyvfA, QmGHwD, uUA, yFcYEr, oYF, igN, ZxyOaQ, fesY, mwapzs, lDuym, fBltC, euGwF, Ymmee, NENLT, yXm, xvyPs, WSHKcJ, zQc, rbiT, uTJ, QqR, wlWMv, rFpAm, psOKt, JDSH, NcH, nLlsc, iqL, QpBKH, fWv, mOiKp, LJx, hAK, THkJ, pIlpS, yfgsUW, zPvNw, njkTX, eyokn, BHox, rhfLai, laNC, tAEYX, HDv, Wiio, OhY, RuzXD, jatmTA, nju, DYR, xViBEl, tYxRV, xEK, gyr, ghbG, KtREZ, CqFQtL, RJroUN, QwX, PNipL, zdJPAx, ffi, rbK, Bqp, eLqE, XDKrW, Drub, NqKi, RKnsZW, nax, Wewhtl, ASFwDF, UaGdy, qiN, GWmJO, WKcNsP, sweF, UNh, MFzH, ghMIsN, cYHGm, qBV, lgYfqQ, deVLE,
