This caboose was built in 1881 and was originally used by the South Pacific Coast Railroad. In 1902 the car was transferred to the Nevada & California RR (Southern Pacific), and given the number No16. It was used in Maintenance of Way service (railroad maintenance). In 1947 it was re-numbered No401. At times it carried people as well as freight, but reverted exclusively to caboose service until the narrow gauge shut down. Placed on display in 1960 at Laws, it was re-activated with repairs in September 2017 for duty as a passenger/caboose car behind Engine No18 during the Slim Princess Reunion.
