0-6-0PT Class 97xx Condensing Pannier Tank GWR Profile and Models

The 9700 Class, or 97xx class, pannier tanks were a direct development of the 5700 class. The prototype for the class, No. 8700 (later No. 9700), was a rebuilt 5700 locomotive. They were specifically for working on the Hammersmith & City line between Paddington station and Smithfield Meat Market. They replaced Metro and 633 class locomotives. The eleven locomotives in the class had condensing apparatus that fed the exhaust steam back into the water tanks. To work over the electrified underground lines, the 9700 Class locomotives had a special type of ATC equipment that lifted clear of the centre rail and had tripcock brake valves that matched the London Transport signalling system.
