Lancashire & Yorkshire 2-4-0 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class unknown (Locobase 8404)

Data from Samuel Rendell (M. I Mech.E), "The Steam Locomotive: Fifty Years Ago and Now", read Saturday, 13 January 1906 and published in the Transactions of the Manchester Association of Engineers 1906 (January to March). See also "Old Locomotives, Lancashire and Yorkshire Railway", The Locomotive Magazine, Vol XIII (15 January 1907), p. 16.

William Jenkins's design was typical of L & Y engines of the day, being relatively low-powered and soon overmatched by traffic demands. The LM report offers a photograph of the Marshall, one of the L & Y locomotives of the time, although it cannot be confirmed as belonging to the class described by Rendell.


Class unknown (Locobase 8968)

Data from C J Bowen Cooke, "British Locomotives", (London: Whitaker & Co, 1894).

Bowen Cooke says that Aspinall designed these tanks to handle heavy passenger traffic, especialy between Manchester and Oldham, Rochdale, and Blackburn. Half of the 24 1/2 miles between Manchester and Blackburn lay on rising gradients of about 1.35% and the class was expected to move 13 coaches that, with the engine, weight 250 long tons.
