1. Why use this guide?

If you haven’t already read the introductory guide to Police you should do this first as the information in the introductory guide is not repeated here.

This guide explains how to find police entry books, registers, pension and other useful records relating to staff of the London Metropolitan Police and the Transport Police.

2. Using our catalogue

Our catalogue contains descriptions of our records. You can search it using keywords and dates, and you can restrict your search to certain government departments or record series.

Use our help page to find out how to search our catalogue effectively.

3. Essential information

3.1 Metropolitan Police

The National Archives has a substantial collection of Metropolitan Police staff records, but not all have survived.

When using these records you might come across the following abbreviations in records such as registers of leavers:

  • RP – resignation permitted
  • RR – required to resign
  • CO – Commissioner’s Office

3.2 Railway and Transport Police

The National Archives has administrative records relating to the Railway and Transport Police, but not records relating to its investigation of crime.

  • Great Western Railway Company (GWR)
  • London Midland and Scottish Railway Company (LMS)
  • London and North Eastern Railway Company (LNER)
  • Southern Railway Company (SR)

You can search our catalogue using these company names to find relevant records.

6. Background

6.1 London Metropolitan Police

It might help when searching for records to know that:

  • the Metropolitan Police Act 1829 defined the Metropolitan Police District as an area about 7 miles radius from Charing Cross, London
  • the second Act in 1839 extended this to about a 15 mile radius from Charing Cross and included all of Middlesex
  • in 1869 this area was divided into four districts, each of which had a number of divisions (see below)
  • from 1860 to 1934 the Metropolitan Police also had responsibility for the police of the Royal Dockyards and military stations Portsmouth, Chatham, Devonport, Pembroke and Woolwich
  • from 1914 to 1926 they also had responsibility for Rosyth in Scotland

If you know the division an officer worked in, you can extend your research to include looking at divisional records. Where records mention an officer’s division they often use the following letter codes:

  • No. 1 District: G – Finsbury; H – Whitechapel; K – Stepney; N – Islington; and Thames Division
  • No. 2 District: D – Marylebone; E – Holborn; S – Hampstead; X – Paddington; Y – Highgate
  • No. 3 District: A – Whitehall; B – Westminster; C – St James’s; T – Kensington; V – Wandsworth
  • No. 4 District: L – Lambeth; M – Southwark; P – Camberwell; R – Greenwich; W – Clapham
  • F Division – Covent Garden
  • J Division – Bethnal Green – added in 1886
  • Z Division – Croydon – was formed in 1921. Croydon had previously been included in W Division
  • Q Division – Wembley – was formed in 1965. Wembley was previously X Division
  • Division letter codes I, O and U were never used

Maps of the districts and their changing boundaries can be found in record series MEPO 15.

6.2 Railway and Transport Police

It might help when searching for records to know that:

  • following the Railways Act 1921 the four largest railway groups had their own police force controlled by a Chief of Police
  • during the Second World War the railways were run by the Railway Executive Committee, under which was the Police Committee made up of the four Chiefs of Police
  • after the war the railways were nationalised and a national railway police force was established
  • in 1949 the British Transport Commission Police was created – incorporating the old four railway police forces as well as several minor canal and dock forces
  • in 1958 the London Transport Police were absorbed into the British Transport Police
