Interior of the baggage-combine (later a baggage-RPO) car used as a shed shown in photo 60-16. The lettering high above the door reads "C.P. 4". Originally built in 1881 for the Carson & Colorado, it was altered over the years to include an RPO. About 1900, the combine smoking section was eliminated, just leaving the expanded baggage and RPO sections. Renumbered in 1920s as "CP 4" because the narrow gauge was then a part of the Central Pacific company owned by SP. Information from Brian Norden, 4/29/2012. Keeler, CA. January 11, 1960.
