This side-door caboose was built in the 1920s by the Peninsular Railroad to haul cargo that was less than a carload. The Peninsular Railroad Company was a subsidiary of the Simpson Logging Company. In addition to hauling light cargo, this caboose also transported passengers to and from the logging camps along the railroad. Rail was the only form of transportation at the time. In 1936, Caboose 700 became part of the Simpson's private railroad and was used for night trips. They added interior lighting that was battery-powered and would charge the batteries when the caboose was not in operation. In 1946, a phone was mounted on the wall below the cupola, which took one man to connect a wire to a phone line while another man made the phone call. By the 1950s, this caboose was on standby service up until retirement in 1965. It was purchased and displayed in Snoqualmie until moving once more to Shelton to be displayed behind Simpson Logging and a flatbed loaded with logs. They are at the corner of West Railroad Street and North 2^nd Street.
