Indian State 2-6-0 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class Class O (Locobase 3184)

Data from E L Ahrons, The British Railway Locomotive, 1825-1925 (London: Locomotive Publishing Company, 1926).

Virtually identical to the O class 4-4-0s, but with much smaller drivers and a long gap between the lead truck and the first driver.
