Leek & Manifold Valley 2-6-4 Locomotives in Great_Britain
Class Details by Steve Llanso of Sweat House Media
Class E R Calthrop (Locobase 11173)
Data from Armistead Cay, "The Leek And Manifold Light Railway," Page's Magazine, vol 5 (1904), pp. 113-123. See also the 1933 newsreel"A Quaint Little Railway," British Pathe film-archive site at [
] and Chasewater Stuff's description of the line at [], last accessed 8 July 2011.
The second of the two was named J B Earle.
The Pathe newsreel's opening card summarizes the L & MV's reputation:"Hidden away in the heart of the Manifold Valley, Derbyshire, runs a queer little railway, whose traffic is just milk." The film shows a standard-gauge wagon being pushed onto a platform whose width is less than the wagon's gauge. A brakeman then operates a foot pedal to raise the platform, and thus the wagon, clear of the track. When the 2-6-4T pulls away, the viewer can see that the platform rolls on the much narrower gauge of the L & MV.
The L & MV operated for about 30 years from 1904 to 1934.
