Detroit & River Saint Clair 2-4-2 "Columbian" Locomotives in the USA

Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 12286)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 21 p. 223. Works number was 16010 in June 1898.

The specs required from the Panorama Route stipulated that the coal and water supply to suffice for a 40-mile run. Baldwin delivered this small tank that used a boiler made up of a thick bundle of vertical tubes. A "conveniently located" condenser was able to take all of the steam diverted from the cylinders. Sixteen circulating tubes in the lower tube sheet, each 2" in diameter and 10 feet long (3.05 m) conveyed the coal to the firebox.

Originally bought by the International Construction & Improvement Co for construction, the 5 worked for the D & RSC when it opened. When that electrified, the sturdy tank went over to the Detroit, Mount Clemens & Marine and when that one electrified, the Despatch Construction Company bought the engine.
