Class Details by Steve Llanso of Sweat House Media

Class 6 (Locobase 15283)

Data from DeGolyer, Vol 72, pp. 256. Works number was 57971 in August 1924.

This small Prairie plantation tank spread its weight over five axles on the 40 lb/yard (20 kg/metre) rails of the ISC's main line. Branches were laid with even lighter 35 lb (17.5 kg/metre) rail. An oil-burner, the 6 could use a straight stack.
