Kwansai 0-6-2 Locomotives in Japan

Class Details by Steve Llanso of Sweat House Media

Class 105 (Locobase 12864)

Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 28 p. 167. Works numbers were 27252-27253 in January 1906. A third intended for the Imperial Government Railway was produced as works number 32662 in February 1908.

Coal capacity is shown as 65 cubic feet.Another spec note detailed the mileage required from oil cups. Those that couldn't be reached except from engine needed to be large enough to provide lubrication for 100 miles (161 km).Those that could be reached would find 50 miles (80 km) sufficient.

Locobase puzzled over the distinction, but concluded that the driver or fireman would need to refuel the 100-mile cups. The others could be topped off from the ground during a station stop.

"Kwansai" might be a variant spelling of Kansei.
