Unspecified 2-8-2 Locomotives in India
Class Details by Steve Llanso of Sweat House Media
Class BESA/HT (Locobase 4254)
Data from [
], last accessed 24 June 2007; and "2-8-2 Type Shunting Tank Engine" locomotive diagram (Indian State Railways), archived on the Rail Enthusiast website's BG BESA class locomotives page at [], last accessed 31 March 2024.
Mikado Heavy Tank of the British Engineering Standards Association array of standardized Indian locomotives. The diagram shows the engines going to the East Indian Railway and the Oudh & Rohilkand Railway.
See the HP 4-6-0 for full description of the BESA intention and varying views of its utility. And compare its dimensions and factors to those of the Pittsburgh-produced Mikado tanks that were delivered a few years earlier (see Locobase 4088)
