Reorganisation[edit]From 1900, several railway companies re-organised their police forces. The London, Brighton and South Coast Railway virtually reformed their police force from scratch in that year, followed by the Great Eastern Railway, the North Eastern Railway and Midland Railway in 1910, the Caledonian Railway in 1917 and lastly the Great Western Railway in 1918.
Inter-war years[edit]The Railways Act 1921 amalgamated over one hundred separate railway systems (of which about 20 had organised police forces) into four groups:
The Great Western Railway
The London and North Eastern Railway
The London, Midland and Scottish Railway
The Southern Railway
Each had its own police force controlled by a Chief of Police. These four forces were organised in the same way; each split into a number of divisions headed by a superintendent, divided into a number of divisions posts led by an inspector. Detectives worked with their uniformed colleagues at most locations. Many 'non-police' duties were retained however, with officers acting as crossing keepers or locking and sealing wagons.
World War II[edit]During the war, the strength of the railway police doubled. With many men conscripted, special constables and women police were again employed.
They seem to have been around during the second world war if the above can be relied on from Wiki.
