In the UK the use of modern diesel multiple units was pioneered in [[Northern Ireland]],{{citation needed|date=November 2017}} although a number of other railway companies also experimented with early DMUs (including the Great Western and the London Midland Scottish). Notable examples include the [[British Rail Sprinter|Sprinter]] and [[Bombardier Voyager family|Voyager]] families, and the newer [[British Rail Class 395|Javelin]] trains.

The [[London Underground]] passenger system is operated exclusively by EMUs. Work trains on the Underground employ separate locomotives, some of which are dual battery/live rail powered.

In Northern Ireland the majority of passenger services have been operated by diesel multiple units since the mid-1950s under the tenure of both the [[Ulster Transport Authority]] (1948–1966) and [[Northern Ireland Railways]] (since 1967).
