Yep, N&W class GS built in 1920 and retired in the mid-30s. Looks like the top eave is rather wobbly on that one. http://www.nwhs.org/archivesdb/detail.php?ID=19939 Hope New Haven had a big rotary dum

These cars employed a somewhat unusual truck setup without a bolster. The weight of the car was carried directly by the truck sideframes. The truck had a lightweight spider casting for the center pin.

There is this critter, assuming it's not secondhand. http://searcharchives.vancouver.ca/uploads/r/null/9/2/926163/0070735b-efbf-4a69-912f-629d37900496-A28805.jpg David Thompson

Looks like a welded underframe, too. David Thompson

The James Lane roster of original USRA twins is in Railroad History #128. Copies were built from 1920 to 1928 or so, when most railroads shifted to offset-side hoppers or their own homegrown designs.

The combination of 1880cf and 30'6" inside length almost always equals USRA twin. The cars with 19xxcf were likely panel-side rebuilds, and the cars with 2055cf were the offset-side derivatives that N

The original USRA specifications showed the typical vertical staff handbrake for both 50- and 70-ton hoppers. The use of a ratchet handbrake on the cars actually built may have been an effort to placa

It should also be noted that the Virginian AX-1s were 10'4" IH versus the 10' even of the PRR car. David Thompson

Might be less involved to remove the roofwalk and file down the raised panels, depending on how many cars you have to do. David Thompson

That was the car that PRR backdated for display at the 1939 World's Fair. It eventually found its way to the Railroad Museum of Pennsylvania. David Thompson

There was a large disbursement of privately-owned hoppers and gondolas circa 1922, prompted by one of those ICC rulings. A few of the larger fleets stayed private (Berwind, Westmoreland, Koppers), but

Did the R-40-4 and R-40-8 classes have four poling pockets or two? David Thompson

3000 cf was pretty large compared to the typical cement car of the day. N&W got about the same result (HC-3) by adding a fourth bay and enlarging the rest of the car, though. David Thompson

"PGH. 5.28.07" No idea if that's McKees Rocks, Alleghany, or neither. David Thompson

The Sunshine 6 and 10k (I think, I'd have to check) X-3s were sold out when I tried to order them a year ago. I did get an X-5 kit, though. David Thompson

MKT or N&W? I don't think the details of the MRS car match either of those, though. David Thompson

Yep, 62.1 and 62.5 are NLA. David Thompson
