The London and North Western Railway (LNWR) Class G2 is a class of 0-8-0 steam locomotives. 60 were built at Crewe Works in 1921–1922. Uniquely amongst classes of LNWR 8-coupled tender engines, they were not rebuilt from or into other classes. Slightly confusingly the LNWR Class G2a is sometimes considered a subclass, but not in this article. They were classified by the London, Midland and Scottish Railway (LMS) as 5, from 1928 7F.

Numbering

The LNWR used a lowest available number numbering system, meaning that numbers were somewhat haphazard. After the grouping in 1923, the LMS renumbered them 9395-9454 in order of build date. All were inherited by British Railways (BR) upon nationalisation in 1948. BR added 40000 to their numbers so that they became 49395-49454.[1]

Withdrawal

Withdrawn 1959-1964.
