British Transport Police was created in 1948.

The British Transport Police are separate to the regular police force, as they only patrol railways and other modes of transport. The latest jobs can be found on the BTP website, along with information about the work they do.

The British Transport Police are responsible for all legal and public safety issues on the tracks, in the trains, on and around the stations.

They patrol in and around railway stations, accompany football fans travelling to and from games, and keep order in pubs, shops etc, that are close to the stations.

The Police and Police Force were invented by the British and there are police force's in every country in the world.

As for the best i would have to say Hong Kong police force as they were based/trained by British S.A.S special forces.

British Air Transport was created in 1932.
