The London Midland Region (LMR) was one of the six regions created on British Railways (BR) and consisted of ex-London, Midland and Scottish Railway (LMS) lines in England and Wales. It was abolished on sectorisation in the 1980s.

Territory

The LMR's territory consisted of ex-LMS lines in England and Wales. LMS lines in Scotland became part of the Scottish Region , whilst those of the Northern Counties Committee (NCC) in Northern Ireland became part of the Ulster Transport Authority (UTA).

The other regions formed were the Eastern Region , the North Eastern Region , the Southern Region and the Western Region.

The LMR's territory principally consisted of the West Coast Main Line (WCML) and the Midland Main Line (MML) south of Carlisle and the ex-Midland Cross Country route from Bristol to Leeds.

During the time of the LMR's existence there were a number of transfers of territory to and from other regions. A few of these are:

• London, Tilbury and Southend Railway to the ER.
• Lines in South Wales and West of Birmingham to the WR.
• The Great Central Main Line from the ER.

Locomotives and rolling stock

The LMR inherited ex-LMS types of steam locomotive. Initially, an M prefix was added to numbers but later 40000 was added instead, giving numbers of ex-LMS types in the 4XXXX and 5XXXX series.

The LMR initially continued building ex-LMS types, particulary black fives, Ivatt 2MT, two Duchesses, and paper rebuilds of Royal Scots and Patriots.

West Coast Main Line electrification

In the 1960s, the West Coast Main Line was electrified between London Euston and Glasgow and Edinburgh.
