All About Postage Stamp Trains
Roco's model is generic enough to pass for any number of 42-foot fishbelly flatcars. The prototypes were most often found on quarry railroads hauling big blocks of stone, or at steel mills moving iron ingots. They weren't seen out on the mainlines as often as their longer brethren, which were frequently carrying tractors, tanks and other equipment.
Note: Flat cars that came in train sets or cardboard boxes do not have brake wheels. Flat cars that came in plastic boxes have brake wheels, although they're frequently lost or broken off from handling.
NOTE: There's a potential conflict in the road codes. 350 is unambiguously Rio Grande, since it appears on a cattle car insert, as well as the 1967 catalog and 1967 Service Manual. However, there's a box marked 4881/350, yet I've found no evidence that a Rio Grande flat car was ever released. The box contains a Norfolk & Western flat.
