The Constituent Forces Project was undertaken to compile a complete historical list of all the police forces which eventually amalgamated into what we now know as the British Transport Police. During the course of this research, however, a number of other similar RDC police forces were discovered, which although they cannot be tied directly to the BTP’s family tree, are considered worthy of inclusion – lest they be forgotten. Where no link has been found this is noted in the table.
This Constituent Forces Index has been compiled by Ed Thompson over a period of two years. Great care has been taken to ensure its accuracy and each entry has been traced to a source. However it has not been possible to confirm a small number of the sources. The list is not definitive, therefore Ed would welcome your comments on any errors or additions you may have. He can be contacted at the email address shown on the Projects page.
There were several “Joint Stations”, such as Bristol Temple Meads, Bradford Exchange and Birmingham New Street, where more than one company operated. Very often the police have been referred to as Joint Railway Police at these locations. However it has not been established if they were a special force set up for a particular station or if they retained their separate company status.
As at 2019, there are two-hundred and forty-eight forces shown.

Notes:
[1] On the 6th June 1897 the Bute Dock Company changed its name to the Cardiff Railway Company. Although it was intended that the Police force should follow suit to become the Cardiff Railway Police, it did not do so, and remained known as the Bute Dock Police until absorbed into the GWR Police in 1923. This despite the fact that there are occasional references to the Cardiff Railway Police.
[2] On the 31st August 1848 the Birmingham & Oxford Junction Railway was purchased by the Great Western Railway; this was two years before the railway line opened. The B&OJR continued construction / operation for some period after 1848 under its own name before absorption into the GWR. During this period Constables were employed, but it cannot be definitively stated whether they wore the badges of the B&OJR or GWR.
