Those cars are complete foobies. PRR did own some wooden reefers in PRR paint schemes, but these were all prior to 1930. In the 20's, the PRR cars were all transferred to Fruit Growers Express (FGE) ownership and reporting marks. By the steel reefer era, all PRR freight refrigerator traffic was in FGEX, WFEX (Western Fruit Express), National Refrigerator (NRCC), or Burlington Refrigerator Express (BREX) cars. PRR was part of a group of railroads that owned all of these refrigerated car lines.
These Lionel VL PRR steel reefers would go great behind one of the new PRR-lettered Santa Fe 2-10-4's, which are also foobies.
