Bombay, Baroda & Central India 2-8-0 Locomotives in India


Class Details by Steve Llanso of Sweat House Media

Class 100 (Locobase 10633)

Data from "Consolidation Goods Loco, Bombay, Baroda & C I Ry", The Locomotive Magazine,Vol XIII (14 December 1907), p. 212.

This class of Consolidations was derived from the HG design drafted by the British Engineering Standards Association (BESA), but had cylinders measuring 1 inch greater in diameter.


Class G (Locobase 20884)

Data from "Recent Locomotivdes by Messrs. Arrmstrong, Whitworth & Co., Ltc, Locomotive News and Railway Contractor, Volume XI [11], No 5 (10 March 1922), pp. 146-149. Works numbers were 69-93 in 1921.

The LNRC report was based on an AW catalogue released in 1922. The AWs repeated a 1908 Ten-wheeler order from Locobase 10633, but increased cylinder diameter by 1" (25.4 mm). (The 1908 engines were based on a BESA design, but had increased cylinder diameter by 1".)


Class unknown (Locobase 12733)

Data from "Some Foreign Compounds", Railroad & Locomotive Engineering, Volume 8, Number 1 (January 1895), p. 29.
