Indian Railways 0-8-0 Locomotives in India

Class Details by Steve Llanso of Sweat House Media

Class IRS/XG (Locobase 4268)

Data from "'XG' Indian Standard (0-8-0) Type Locomotive" Superheater Company, featuring a Beyer, Peacock & Co. Design credited to Messrs Bender, Palmer & Tritton.

Part of a series of designs created in the mid-1920s to meet Indian railway equirements. This was the larger of two eight-coupled freight design. MLS superheater, multi-valve regulator type header.

According to S. Shankar of India's National Rail Museum website -- [] -- these engines were heavy switchers (hump shunters) on the North Western Railway of India. Their heavy weight caused so much damage to the track that they were converted to a 2-8-2 arrangement in 1943.

[] notes that these had "...a wider firebox and other improvements to handle low-grade coal."
