FC FMThe FM flat was the stalwart of the Pennsy's flat car fleet until the F30A was introduced. Between 1902 and 1913, the FM were built by Altoona Car Shops, Pressed Steel Car, American Car & Foundry, Cambria Steel, Standard Steel Carm, and Mount Vernon Car.

The FM was a 40' fishbelly car of pressed steel and riveted construction. Delivered with archbar trucks, they were replaed by the ubiquitous 2D-F8 truck.

PRR 473409 FM containercar

Beginning in 1928, the Pennsy began a service of transporting less-than-carload (LCL) containers. Over 800 FM flats were modified to secure such containers. This service continued until October 1950 when J. M. Symes ordered the retirement of over 3,000 merchandise containers and for all modified FM cars to be returned to general service. Container LCL service was directed to boxcar LCL service.

Beginning in November 1955, 10 cars were converted for pulpwood service with the addition of end bulkheads (470325-470334). This service lasted unil April 1964.

Many FM found their way into MoW service.

The FM has been offered in brass by Railworks and Crown ; and as a resin kit by Sunshine (out of business) and Funaro & Camerlengo. The Red Caboose offering is incorrect. Mount Vernon Shops offers FM decals.

Ted Culotta has an excellent article on modeling the FM.
