British Transport Police

The British Transport Police (BTP) (Welsh: Heddlu Trafnidiaeth Prydeinig) is a special police force[4] that polices those railways and light-rail systems in Great Britain for which it has entered into an agreement to provide such services.[5] British Transport Police officers do not have any jurisdiction in Northern Ireland,[6] where policing of the railways is the responsibility of the Police Service of Northern Ireland.
