The Shay-type locomotive is a large steel vehicle whose most prominent features include an engineer’s cap, oil fuel bunker, large boiler and exposed engineer. The Shay-type geared system gave the engine great pulling power, but was rather slow and sounded like a noisey truck in first gear. The locomotive was built in 1924 and is 41 feet 2 inches long, 16 feet 2 inches high and ten feet wide.

The caboose was constructed in the 1920’s of wood and steel hardware and trucks. The most obvious feature on No. 700 is the cupola located midway along the length of the body. Other important body features include the large sliding doors located on either side to the rear of the cupola and the covered platforms located at both ends of the car.

Both the locomotive and caboose have maintained their integrity as historic objects and their present location on the original right-of-way is authentic.

The locomotive and caboose were placed on the National Register of Historic Places in 1984 and on the Shelton Historic Register in June of 1995.
