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

Does anyone know of a photo of the DYLX covered hoppers (Dri-Flo types, I believe) BESIDES the one in the Classic Freight Cars book? I'm looking for an image prior to the formation of

Larry posted his comparison spreadsheet showing a straight line fleet-percentage vs observed-percentage for each railroad. I then said that one really needs to compute a standard deviation

Tim, Gould made a lot of trucks. Which one did you have in mind? Brian Leppert Tahoe Model Works Carson City, NV

Soo That correcting my error. I need Spokane, Portland & Seattle can be added to the list. These were ex- GN gons aquired in the '50s and converted to wood chip cars. I am aware of SAL B-5 boxcars

Al, A couple of folks I know that have built these have used the old Cape Line Pilchner Patent truck. These are now available from Bethlehem Car Works, I believe. Chuck Hladik Rutland
