Western Refrigerator Line

All of the WP's 2,000 pieces of existing rolling stock were placed into PFE's car pool, including an additional 775 units ordered that year.

Units arriving after the contract's execution were painted yellow-orange, were lettered and numbered according to PFE's classification, and were emblazoned with WP's "Feather River Route" emblem on each side.

The units were outfitted with electrically powered circulation fans and other improvements required to bring them up to current standards.

Facing the need to invest millions of dollars toward the purchase of new, mechanically cooled refrigerator cars, the Western Pacific chose instead to become a partner in the PFE's rival Fruit Growers Express in June of that year (which, at the time, controlled 24,000 mechanical reefers and 3,500 refrigerated tractor-trailer sets).

A handful of the original wood refrigerator cars were converted for ice service on the WP system.
