Seiwa 0-6-0 Locomotives in Japan


Class Details by Steve Llanso of Sweat House Media

Class 22 (Locobase 9634)

Data from Catalogue Descriptive of Simple and Compound Locomotives built by Brooks Locomotive Works, Dunkirk, NY (Buffalo, NY: Matthew-Northrup Company, 1899). See also Consul-General Gowey, "Length of Railways in Japan as of July 31", letter of 24 August 1898, in Consular Reports - December 1898, Volume LVIII, No. 219, US House of Representatives, 55th Congress, 2nd Session, Doc. No. 565, Part 4 (Washington, DC: GPO, 1898), p. 565. Works numbers were 2862-2864 in December 1897.

This tank had relatively short tanks flanking a long boiler. Its vestibule cab suggests a cold operating environment. In 1898, CG Gowey's report showed that this railway was authorized to build a 64 3/4 mile (104 km) line.
