Signal Fact 61

British Railways developed its automatic warning system (AWS) in the 1950s.

General introduction started towards the end of the decade.

Over time the various railway companies reoganised and the boundaries of the various traffic and engineering areas changed which can sometimes make it difficult to locate and research signalling information. As one might exxpect, the traffic and engineering changes did not always take place at the same time! Nationalisation and 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 or through other sources. Some of the information shown is derived from such copies of the engineeting notices as we have in our digital archive. Looking through this page may well assist in determining where to look for information about specific places of interest at different time periods.

London Midland & Scottish Railway

From 1928 engineering notices seem to have been published fortnightly with a supplement in the intermediate weeks.

Western Division (Former London North Western Railway lines).

Cheshire Lines.

Southern Railway

Alterations to signalling were published in a series of notices with numbering restarted at 1 with the first notice of each year.

1948 Nationalisation

The bulk of the lines operated by the “Big Four” railway companies were divided into six Operating Areas. Later these were called Regions:

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.

Initially the Regions generally perpetuated the arrangements in place immediately prior to nationalistation.

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

1949 Weekly Notices

From week 13 (commencing 26th March), possibly earlier, the internal format of the weekly notices was standardised across all regions. The sections were:

The London Midland Region fortnightly notices became weekly notices: week 6 was for one week followed by week 13. However, the situation on Western lines is confusing as week 8 was for 2 April 1949, week 13 for 7 May 1949 and week 37 for 22 October 1949.

1957 Boundary Alterations

From 12.1 am on Monday 4th March various lines were exchanged between the Eastern and North Eastern Regions and London Midland Region lines in the Leeds and Wakefield areas transferred to the North Eastern Region. An asterisk (*) indicates that the transfer had already taken place.

At the same time, divisional boundary changes took place in both the London Midland and North Eastern Regions. [North Eastern Weekly Notice 8].

1958 Boundary Alterations

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 usually 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.

The London Midland Region took the opportunity to transfer various lines from the Liverpool District into the Western Lines.

1962 London Midland Region Traffic Area Reorganisation

From week 46 (10am Sunday 18th November) the traffic control boundaries were altered with lines north of Crewe (Coppenhall Junction), Goostrey, Sandbach Junction (Middlewich Line), North Rode and Christleton moving from Western Lines to North Western Lines.

From the same date the former Great Central lines from Marylebone to Culworth Junction were transferred from Midland Lines to Western Lines. The same notice mentioned that trains were being diverted to Marylebone whilst Eusston was being reconstructed and the previous week's notice mentioned that an extract of the Midland Appendix had been produced for trainmen diverted to Marylebone.

Midland Lines transferred to North Western Lines as part of this process (date unknown) were Miller's Dale Lime Co.'s Sidings Down Distant Signal to Manchester Central via Cheadle Heath and via Stockport T.D., Miller's Dale Junction to Ashwood Dale, Chinley to Totley Tunnel East, Macclesfield Central to Manchester (Piccadilly) via Rose Hill, Hayfield to Manchester (Piccadilly) via Guide Bridge and via Belle Vue, Manchester Central and Godley to Liverpool Central and branches, Dunford Bridge to Manchester (Piccadilly).

1963 Boundary Alterations

From Southern to Western

From Western to London Midland

From April four weekly notices containing the accumulated Section D items were introduced to reduce printing the same information every week. The weekly notices still contained Section D items that needed to be published before the next four weekly notice appeared.

Supplementary Operating Notices continued to be published until 1971.

Sectorisation

The commercial aspects of the railway were transferred to the new railway business sectors whilst operations remained regional.

1989 Eastern Region Sectional Appendices Reorganised

In 1989 lines were moved from the Eastern Region Southern Sectional Appendix (BR 30015/1) dated February 1988 to the Eastern Region Northern Sectional Appendix (BR 30018) dated April 1986 in a series of stages. The Anglia Region lines remained in BR 30015/1 pending issue of an Anglia Region Sectional Appendix.

Stages 1 & 2 were detailed in Weekly Notices NN&NS18-20; stages 3 to 5 in NN&NS26-31; and stage 6 in NN&NS36-39.
