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.
