This 31' Bay Window Caboose is painted white with multi-colored Southern Pacific Railroad Police Shield and black lettering.  It was built by International Car Co./PACCAR.  In an attempt to combat theft on trains, Southern Pacific painted a number of C-50-9 Class cabooses with Police badges and "Police" lettering.  They were used on trains, along with an SP Police Car (Auto) pacing the train, to deter people from boarding and stealing or damaging lading and railroad equipment.  Along with the regular train crew, SP Railroad Police or Special Agents, rode in the caboose to monitor the train.
