Bombay, Baroda & Central India 0-6-0 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class 181 (Locobase 13609)

Data from "Some Foreign Compounds", Locomotive Engineering, Volume VIII, No 1 (January, 1895), p. 29.


Class unknown (Locobase 6380)

Data from Vulcan Foundry catalogue, ca. 1920 ([]) and [], which gives the information that these relatively powerful freight locomotives were VF works #1606-1617.


Class unknown (Locobase 13581)

Data from John Robinson, "Modern Locomotives", Van Norstrand's Engineering Magazine, Volume X, No LXI (January 1874), p. 46.

In his discussion of then-modern locomotives, Robinson reported that this engine would draw 694 long tons on the level at 25 mph. Hauling an average load of 490 tons, the engine burned 59 1/4 lb of coal per mile. "A peculiar feature of this engine was the position of the hind axle under the firebox, permitted by the shallowness of the end of the latter [because the grate sloped down from back to front]," said Robinson. There were two purposes to this stubby arrangement. It allowed "... a comparatively short wheel base and an equable distribution of the weight of the engine."
