Lancashire & Yorkshire 2-6-2 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 26 (Locobase 2315)

See Ahrons (1927) and Fowler's Illustrated Locomotive Dictionary (1906) for data. HA Hoy design. See also steamindex's summary at [], last accessed 12 September 2015.

According to Metcalf (Lancashire & Yorkshire Railway Locomotives, []), this was Harry Hoy's only original design and it was a failure. They were designed to take corrugated fireboxes, but were delivered with Belpaire fireboxes. They had a water-scoop assembly that allowed the engine to take water on the run.

Quoting Marshall, steamindex noted that the class was intended for the Manchester to Oldham and Rochdale to Bacup services.
