40' FGE R7 Reefer

Prototype Information

After the success of its X23 boxcar, the Pennsylvania Railroad built over 3,500 refrigerator cars of similar design, designated R7, between 1914 and 1915. These cars operated on both PRR lines and its subsidiaries. By 1922, the railroad had leased nearly the entire fleet to the Fruit Growers Express Company (FGE), where it held a financial stake. In 1932, FGE took full ownership of the cars.

Like the X23s, the R7 reefers underwent several upgrades. The railroad replaced arch-bar trucks with 2D-F8 cast trucks, swapped out KD-brakes for AB-brakes, and installed Hutchins Dry-Lading roofs in place of the original lap-seam design. Between 1940 and 1942, FGE transferred more than 250 R7s to its National Car Company (NX) subsidiary for meat service. In the early 1950s, National leased a small group of R7s to Mathieson Chemical for dry ice hauling. The R7s stayed in regular service through the late 1950s.
