Unfortunately there are not enough different models available to even begin to come close to "National Averages".Armand Premo

Tim, Here's some railroads I know of that used the double truss coil- elliptic sprung 40 and 50 ton trucks, with or without spring planks: C&O, CGW, WM, BAR and Erie used them on some or all of

You mean 46759? There is no 46795 in the 1940, 1950, or 1953 ORER's.

Steve, I don't see any 'danger' at all, as long as you -ASSIGN- cars to run on the layout in the proportions to the national fleet. In other words, suppose you have 103 box cars and Railroad XYZ only

Good work, Larry! That's what I'm talkin' 'bout! A 40 car train with 9 SP (not counting T&NO) box cars.. More than 5 times the 'average' value of 1.6. And the peak CMO value at 20 times its

Al - C&O battleships can reasonably be modelled from Buckeyes. N&W early battleships used Pilchers which are available from Bethlehem Car Works. The Lewis trucks are unlike anything on the market

Brian sent me a great photo of a 3rd sideframe with these springs -- This one is a Buckeye casting (circle-B foundry mark)... very interesting. Anyone know who besides DT&I had trucks like this? Tim

What class of cars does UP #46795 Stock car belong to? Rich Yoder PA

I withdraw "several series". Thought I'd remembered them on the A-1 auto cars, which would've implicated some gondolas and flats too, but on re-inspection the A-1 has regular Andrews. Al Brown,

N&W used them on at least its B-1, B-2 and B-3 boxcars. Drawings are available from NWHS here: http://nwhs.org/archivesdb/listdocs.php?index=rs&id=1980 Jim Brewer Glenwood MD

Tony-- After reading this thread for some time, I have to agree with your basic premise. Most major through transcon routes such as the UP in Wyoming would very likely have over a given period,

Absolutely, I should have been more specific... and indicated that the statement applied to someone model, for example, Cajon Pass, or an obscure ATSF branch near Alma ;^) Interesting, in my

Folks, In reseaching the C&O, N&W and Virginian high capacity gons, of the late-teens and early-twenties, one see a great number of experimental 6-wheel trucks being "tried" : ASF Lewis, ASF

Hi Folks I ran my "random train" Excel program for 100,000 iterations to test whether it was working OK. The average number of boxcars per train, by railroad, seemed to properly mirror the national

Brian You may not be aware but the earliest version of those trucks I've seen were cast in 1934 by ASF, while the DT&I cars were built (with different castings from unknown foundry) in 1949. So

I have 5-6 of the DT&I cars located nearby some still have those trucks. I posted some photos to the list years ago 2004 but removed them later. Brian J Carlson P.E. Cheektowaga NY

You mean 46759? There is no 46795 in the 1940, 1950, or 1953 ORER's. ...and ditto for july 1959 dave </HTML>

Brian I was looking at a drawing but now I can't find it -- but now I think I'd rather have those coil-leaf-coil trucks as found on the DT&I 14000-14299 box cars. This spring package was applied to
