A government review in 2015 recommended two options for the future of traffic officers: a single National Infrastructure Constabulary combining the function of the Civil Nuclear Constabulary, the Ministry of Defence Police and the British Transport Police with the traffic officer service; two separate forces: a Transport Infrastructure Constabulary, that would include the traffic officer services, and an Armed Infrastructure Constabulary . As of February 2017 these proposals have been put on hold whilst the three police forces involved explore collaborative working options . </P>
