This locomotive was built in 1924 and is 41 feet 2 inches long, 16 feet 2 inches high and 10 feet wide. The caboose was constructed in the 1920’s of wood with steel hardware and trucks. The most obvious feature on No. 700 is the cupola located midway along the length of the body and the large sliding doors located on either side to the rear of the cupola. The locomotive and the caboose were placed on the National Register of Historic Places in 1984 and on the Shelton Historic Register June of 1995.
