This 40’ box car with double sliding doors is painted brown with yellow ‘Feather River Route’ logo and lettering. It was built in March 1945 by the Mount Vernon Car Company, rebuilt in February 1955, and runs the Southwestern District on Bettendorf trucks. In 1955 the WP had Paragon shops rebuild five 50-ton box cars from the 20201 series with six-foot double Doors and equip them to handle automobile transmissions for the new Ford plant in Milpitas, CA. These five cars were repainted with the “Feather River Route” mid-1950s scheme and renumbered into series 18501-18505.
