Trying to build from scratch an HOn3 Stock Car.  Where can a modeler find the scale of a 30 foot Stock Car or Box Car for that matter?  I have been on NMRA site and it does not cover that.  I even called them and got the run around.  I know there must be a printed sheet of all the gauges that exist on true dimensions from the real thing.
Help Please.  Captain JL

Don't know exactly what you mean by "Scaling" If you need dimensions I would suggest you get a hold of a copy of "Slim Guage Cars" This will give you a good idea of narrow gauge car sizes. Widths could vary between 7'-6" to 7'-11". Top of rails to top of roof walk could be 10'-0". or so. Knowing this should give you a good start on your project.

What I mean by scaling is what would the HOn3 car be in inches that a real car of 30 feet be?  And how high would it be and how wide would it be to be HOn3 scale of the real thing.  See where I am going with this?  If I had no plans (which i do not) and I wanted to build an HOn3 Stock car and that car on the Southern Pacific line was
30 feet long for pictures I can get on my computer and copy that off.  But the problem is getting the dimensions to suit the HOn3 scaling.

You also might try UNDERGROUND RAILWAY PRESS, they have plans for most everything that has been built. Well, not everything, but certainly box & stock cars. As for scale, I believe most are 1:48, but it isn't a problem if you have an HO scale ruler or can get the plans shrunk to 1:87 scale. Check them out.

BTW-there is no such thing as HOn3 scale...it is HO scale, HOn3 gauge, 1:87 scale, 3.5MM equals 1 foot, HOn3 gauge is 10.5MM. I think you need to buy a scale ruler, maybe several with different scales. Just my observation.

Hi,

You seem to be asking what would the size (inches long, wide & tall) of a 30 foot Stockcar used on a Narrow Gauge RR with 3 foot track? (HOn3 - HO being 1/87 and the 3 being 3 foot track width).

I have a set of plans for a Narrow Gauge Colorado and Southern 31 foot stock car, built for 3 foot track. This should be a good example. The plans are drawn for HOn3 and the different measurements are:

length in inches is 4.25",
width in inches is 1.0625"
height in inches is 1.1875".

The next part of your question seems to be "Where do you find this kind of information"? If you are going to model Narrow Gauge and want to scratch build some of your models then you need to get magazines or a few books that feature Narrow Gauge. The information I gave you came out of the Narrow Gauge and Short Line Gazette (NGSL-G). The same information can be found in a book called "Up Clear Creek on the Narrow Gauge", by Harry W. Brunk. His book covers the first 54 articles he wrote for (NGSL-G), his second Book called "More Up Clear Creek on the Narrow Gauge" covers the next 65 articles in the "Up Clear Creek" series and 22 of his other articles. I am not pushing any specific magazine or books but how do you find answers to your question without a few references.

You desparately need to purchase an HO scale rule and some reference materials. Trying to scratch-build using a regular ruler is just asking for a quick end to your railroad dreams.

Purely my opinion...

Just another comment. I don't want to step on your dreams, but maybe you would be better off starting a scratch build of a flatcar, a gondola or even a boxcar before you attempt a cattle car. Don't frustrate yourself by starting too big a project for your skill levels. Please accept this message with only good intentions.

Many thanks to all of you that responded to my question.  I am a Communications Engineer by trade. (retired now)  So I deal in facts and figures.  I thought the NMRA would have this type of scaling for all the different gauges in their site.  So when I was asking for the scale dimensions of HOn3 I was certain there must be a published list of how to convert a real 30 foot Stock car to HOn3 size.  I agree with the idea of a scale rule that will give exact dimensions.  Thank you for that.  I know you all will
laugh at this.  I am in Phoenix Arizona for the winter.  I am a misplaced Alaskan.
Most of my Narrow Gauge kits are in storage with my Son in North Carolina.  So instead of bothering him about my stuff.  I decided to build a car just to pass the time.
Yesterday I finally relented and drove 60 miles to Roy's Train World in Mesa, AZ and purchased a Micro-Trains car.  Of course I purchased an Alaska car -White Pass & Yukon RR.  I got the dimensions I wanted off of that car.  Spent 40% off on the car, some couplers, trucks and a section of HOn3 track.  I am ready to build now.  Wish me luck in all this.  Again I thank all of you for your input.  Its nice to know there are some good railroaders out there.  Captain JL

Since you are so close...drive on over to the Clifton/Morenci area...home of 20" gauge. Lots of stuff to see and if you would like a cool one, visit the Cave in Clifton. If you get that far, then go another 40 or so miles to Mogollon, NM. No trains there, but a wonderful place to visit.

OK I think I have the answer you are looking for HO is 1/87 of actual size.

30' length X 12" per foot = 360"

divide 360" by 87 = 4.25" long for an HO scale car.

O scale is 1/48 of actual

S scale is 1/64 of actual

HO scale is 1/87 of actual

HOn3 is also 1/87 of actual
