Career Operators Metropolitan Railway London and North Eastern Railway Class MET: K LNER L2 Number in class 6 Numbers MET:111–116 LNER 6158–6163 Retired 1943–1948 Disposition All scrapped

The Metropolitan Railway K Class consisted of six 2-6-4T steam locomotives, numbered 111 to 116.^[1] They were built by Armstrong Whitworth in 1925 using parts manufactured at the Royal Arsenal, Woolwich, to the design of the South Eastern and Chatham Railway N Class 2-6-0 locomotives. The boilers had been made by Robert Stephenson and Company of Darlington.

Service

The K Class were used on heavy freight trains along London's Metropolitan Railway mainline, including coal to the power station at Neasden,^[1] although there were used on occasional passenger trains. In 1937, all six were transferred to the London and North Eastern Railway (LNER) where they were based at Neasden (LNER) Shed. The LNER numbered them 6158–6163 and classified them as L2 Class.^[1]

Withdrawal

All were withdrawn and scrapped between 1943 and 1948.
