Regional & Other Boundary Changes

This page should be regarded as “Work in Progress”. The webmaster will welcome additional information for this page.

Over time the boundaries of the various British Railways Regions changed which can sometimes make it difficult to locate and research signalling information. Privatisation did not stem this flow of change as Railtrack and Network Rail continued the ingrained habit of reorganisation.

On this page are recorded some of the implemented boundary changes that were published through the medium of weekly engineering notices and the amendments to the timetable appendices. Looking through these lists may well assist in determining where to look for information about specific places of interest at different time periods.

1948 Nationalisation

The bulk of the lines operated by the “Big Four” railway companies were divided into six British Railways regions:

• Eastern. The Great Eastern and Great Northern sections of the former London & North Eastern Railway, south of Shaftholme Junction; Kings's Lynn Docks & Railway; Midland & Great Northern Joint Railway.
  
  
• London Midland. The London Midland & Scottish Railway lines in England and Wales; Cheshire Lines Railway; Mersey Railway.
  
  
• North Eastern. The North Eastern section of the former London & North Eastern Railway from Shaftholme Junction northwards.
  
  
• Scottish. The former London Midland & Scottish Railway lines in Scotland together with the former London & North Eastern Railway lines in Scotland.
  
  
• Southern. The former Southern Railway; East Kent Light Railway; Kent & East Sussex Railway.
  
  
• Western. The former Great Western Railway; Clifton Extension Railway.

London & North Eastern Railway lines in the Manchester area transferred to London Midland Region.

The former London Midland & Scottish Railway lines in Northern Ireland (Northern Counties Committee) intially remained under the control of British Railways and were then transferred to the Ulster Transport Authority in April 1949.

1958

In 1958 the regional structure based largely on the big four company boundaries was amended to a geographic one. The nature of the change led to it being often referred to by the term “Penetrating Lines” as the lines that penetrated another geographic region were the ones transferred. The changes were implemented from 12.1 am on Saturday 1st February.
