Photo: Forward Facing Great Northern Rocky (1939)

Photo from the Library of Congress:

A USRA double sheath car that has been re-sheathed and equipped with a Youngstown door. This photo well illustrates the spotting features I mentioned yesterday; the shape of the poling pocket casting, which caps the end of the inset side sill, and the casting that anchors the diagonal rod 1/3 of the way up the end.

Not so evident is the fact that the ends are wider than on the USRA SS cars, those only have to cover the ends of the sheathing which is in line with the side sill. On the SS car the diagonal rod from the sill to the end was replaced by a flat strap on the outside of the sheathing. The diagonal rod wasn't unique to the USRA cars; other double sheathed cars with steel frames built around the same time also used it, most notably the NYC 36' and 40' cars.
