UP 25884 is a CA-11 steel bay window caboose that was built in July 1979. The car was retired by Union Pacific but the details of its disposition are unknown to me. The car was reported to be previously located in Willits, California but is now on a spur behind the restored Petaluma, California depot accompanied by ex-SP, NWPY GP9E number 3804 and a couple flat cars. Images were taken May 24, 2007.
