East & West Yorkshire Union 0-6-2 Locomotives in Great_Britain


Class Details by Steve Llanso of Sweat House Media

Class 4 / N19 (Locobase 6471)

Data from Richard Marsden's LNER site -- [link] (accessed 19 March 2005). This trio was delivered in 1898 to a railway whose steep and sharply curved profile brought the good and the bad in the radial tank layout. The good was the design's ability to handle the curves, thanks to 4" of radial-axle travel; the locomotives also rode more steadily. But that trailing truck represented a decrease in available adhesive weight, which this line needed. They worked the main line between Lofthouse and Stourton and branch lines radiating Robin Hood to the Newmarket, Thorpe, and Beeston collieries.

In 1919, #4 was converted to an 0-6-0ST to answer the adhesion requirement. 5-6 had not been converted when the LNER acquired all three in 1923. 6 was almost immediately scrapped rather than repair a cracked frame. About these locomotives: "The N19s were particularly well suited to this demanding line and the LNER was hard-pressed to find a good alternative." Even so, the 3115 (the only full-blooded N19 to survive Grouping) was withdrawn in March 1928.
