Were the NP, SP&S, and CB&Q the only roads that purchased 52ft
flatcars with 13" side sill and a deep fish belly center sill? Would
any "Q" or SP&S fan be able to help me find a picture of one of their
cars. The cars are similar in construction to the 40ft USRA kit by
Tichy and ERTL, except for the lenth of course.
