GR

GR 166176

GR Load

Between March 1902 and 1907, the PRR turned out over 16 thousand GR's. The cars featured wooden drop ends to facilitate overhanging loads and had Carmer cut levers and safety chains. Over time, the class was retrofitted with steel-sheathed wooden ends and straps that connected the last ribes on either end, presumably as a stiffener.

Built with arch bar trucks, they were eventually upgraded to 2D-F8 trucks.

Around 1943, 580 were converted to FGR flat cars to meet the need for transport of U. S. Army M4 Sherman tanks. Many were also trasferred to MoW service.

The GR were retired by the thousands by the mid-1930s. 198 remained in service as of January 1953.

The LIRR also rostered 133 GR between January 1932 and August 1949.

Funaro & Camerlengo offers the GR as a resin kit. Railworks imported the GR in brass, incorrectly labeled as a GRA. Decals are available from Mount Vernon Shops.

GRA

PRR 859010 GRA

The GRA was not a conversion from GR, but was a new car of its own, using similar design. The GRA was also a 50-ton car, but was a 40'8" car.

The GR side ribs were evenly spaced; the GRA side ribs were evenly spaced except for the two in the center.

Over 14 thousand GRA were built between December 1907 and 1916 byACF, PSC, CSC, SSC and others.

The GRA trucks were also upgraded to 2D-F8 trucks.

520 were converted to FGRA flat cars to meet the need for transport of U. S. Army M4 Sherman tanks. Many were also trasferred to MoW service.

The GRA were largely retired after WWII.

Westerfield offers the GRA as a resin kit. Decals are available from Mount Vernon Shops.

Ted Culotta has an excellent article on modeling the GRA.
