- LNER Thompson Class L1
The
London and North Eastern Railway (LNER) Thompson Class L1 was a class of2-6-4 Tsteam locomotive s designed by Edward Thompson. The prototype no. 9000 was built in 1945, but the remaining 99 were built underBritish Railways jurisdiction in the period1948 -1950 .The Class, at least on paper should have been very free steaming and powerful engines, however in practice they were not suited to the work to which they were assigned. the engines had 5'2" wheels, which would lend it to excellent power at low speeds, such as that required for freight work, however these engines were intended for passenger use. The Speeds required on suburban passenger use wore the engines out in a remarkably short time, axleboxes, crossslides and crank bearings all suffered due the high speeds.
Withdrawals were between
1960 and1962 . None survived to preservation.External links
