Eastern Bengal 4-4-2 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class 133 (Locobase 10276)

Data from "New Engines for Indian Rys," The Locomotive Magazine, Vol VIII (14 Feb 1903), p. 119.

Locobase doesn't know how many of these bogie-radial tanks went into service, but the photo showed a long-striding profile.


Class 254 (Locobase 10721)

Data from "Railway Notes - Eastern Bengal Ry," The Locomotive Magazine, Vol XV (15 July 1909), p. 126.

This was Kitson's bite of the BESA Atlantic apple.
