Norfolk Southern had 44 out of 150 copies in 7/50, but they were on their way out by then.

I'm inclined to say used, since NP doesn't have any hopper orders listed in the annual Railway Age summaries around that time. NP did have them by the end of 1930. David Thompson

I looked around, and the only Pressed Steel order that fits is a batch of 90 cars for Cumberland & Pennsylvania ordered in 1921, which were gone from C&P by 1931. David Thompson

The cars Pullman built in 1931? Page 267 of the 1940 CBC (also Train Shed #5). Cars were CGW 67591,3,5,7,9. David Thompson

It shouldn't. The C&O (and NKP) ARA 1932 cars had a late Hutchins radial roof (which is not the same as the 1920s Hutchins radial). David Thompson

The "Cambre" roof is the same one used on the C&O/NKP ARA 1932 boxes built in 1934. The C&O diagram identifies the roof as "Hutchins", presumably for the manufacturer versus the trade name. David Thom

N&W class B-1 46000-46999, Ralston 1936-7 47000-47499, Pressed Steel 1937 http://spec.lib.vt.edu/imagebase/norfolksouthern/full/NS2892.jpeg http://spec.lib.vt.edu/imagebase/norfolksouthern/full/NS2893

As mentioned earlier, Bethlehem's main freight car facility was the Cambria plant in Johnstown, PA. Corporate simplification in the early 1920s brought about the dba change from Cambria to Bethlehem,

350 cars 7000-7349 from Pullman in 8/27, 100 cars 7350-7449 from Pullman-Standard in 8/37, and 400 cars 7450-7849 from P-S in 5-9/48. There were two photos of the first order in the 1931 CBC, reprinte

Found this while I was looking for C&IM gons; one of the more obscure carbuilders. http://www.midcontinent.org/rollingstock/builders/hicks_loco_freight.htm David Thompson

They were rebuilt with ordinary 7-post sides in (1943, off the top of my head). John Corns' second W&LE book has a few pages on Canton. Started out in a W&LE shop in 1927, was folded up into the SSC s

The NYC system cars were basically the standard USRA twin hopper with offset sides (there were also some 70-ton versions)- not the same as the IC car. SHS has a nice rendition in S. David Thompson

This design started out as the Enterprise offset-side twin hopper shown in various CBCs in the mid-late 1920s. The original design was 34'9" inside length and had stamped corner sills, but the design

That depends on the car in question. The Ralston GS gons certainly did have doors over the trucks, as did some Cambria cars of that era. The broader point about the volume used by the customer is vali

And before Peabody bought the line in 1956, the railroad was St. Louis & Belleville Electric, which had 311 hoppers and 37 gondolas in 1950. David Thompson

IIRC, that's what BLI did for their recent "hybrid" engines: brass shell and mechanism, with injection-molded plastic gingerbread bits. That doesn't work so well for freight cars, though. The future t

Naah, it's a visual trick resulting from the really high contrast level in that photo. If the end actually was recessed, the rounded ends of the darts would be hidden by the vertical rivet strip on th

I've seen an in-train photo in a book (or magazine?) I have, but I don't remember which one. Next time I come across it, I'll try to remember to post up. David Thompson

Aside from what's already been named, Missouri Pacific and Grand Trunk also had rebuilds, and EJ&E had some 70-ton side-dump hoppers built new. David Thompson

The H-7 groups look like the AAR standard to me. David Thompson
