WP 467 was part of a 15 car group built by International Car Company in 1973 and 1974. These were the first steel cabooses on the Western Pacific delivered without roofwalks or end ladders and they were painted an overall bright red paint scheme. When the WP was merged into the UP in 1982, all of these cars were re-classified by the UP. The nine remaining 1973 cars (467 to 475 - the 466 which wrecked in September of 1981 and scrapped ) became CA-16 class cars and the 5 1974 cars (476 to 480) became CA-17 class cars. Only one, the 478, was painted UP armour yellow.

The 467 was retired by Union Pacific in 1986 after being out of service and stored for about a year in Council Bluffs, Iowa. In 1988 the car was generously donated to the Niles Depot Historical Foundation in Fremont, California where it has been on display since 1989. Images were taken on April 15, 2007.
