North Western Railways 0-6-2 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class ST (Locobase 10196)

Data from "Indian Locomotives", Locomotive Magazine, Vol VI (July 1901), p. 119.

This sturdy-looking tank-engine design was used primarily for shunting (switching) although its coal capacity suggests it might have taken a turn on the main line once in a while (or used such low calorie coal that a smaller bunker would have meant a very short work period.)
