This lightweight steel and aluminum car was built as a Postal Storage Car in October 1949 as part of an 11 car order from ACF. It was assigned to MOW service in April 1969, and given the number UP 24436. It was later renumbered UP 904236 in 1975 and was used in service on a wreck train with derrick.

There are several heavy duty workbenches inside the car, along with storage racks at the far end that were once used to store mail and express. Today they are still stenciled for things like rerailing irons, and runaround hoses.

The car was donated to the museum by UP in 1988, and was repainted to this scheme by 1990, and has had very little work done since then, and beyond some ungodly fading paint, it doesn't really need any, being of primarily aluminum construction.

I've been in touch with UP, and it looks like they will donate the materials to cosmetically restore thing thing.
