Liverpool, Southport & Preston Junction 2-4-2 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 5 (Locobase 20662)

Data from "The West Lancashire Railway and Locomotives", Locomotive Magazine, Volume XXIV [24] (15 May 1918 and 15 July 1918), pp. 81, 116. Works numbers were 3072-3073 in 1887.

The other half of a four-locomotive order from Kitson in 1887, this pair differed from the 0-6-2T radial tanks (Locobase 20661) in substituting a leading truck for the front driver set.

Both the LS&PJ and the WLR were sold to the Lancashire & Yorkshire on 1 July 1897. As with the 0-6-2T, the L&Y rebuilt the pair with standard type drivers. Unlike the radial tanks, Horwich Works fitted still taller drivers (68"/1,727 mm). A new standard "renewal" boiler had a firebox offering 18.8 sq ft (1.75 sq m) of grate area. The bigger boiler presented an additional 103 sq ft (9.57 sq m) composed of 1,070 sq ft (93,82 sq m) in the tubes, 94 sq ft (8.73 sq m)in the firebox or 1,164 sq ft (108.14 sq m) evaporative heating surface area.
