tube train
English
A tube train at Mornington Crescent station on the Northern Line.
Tube trains also come above ground outside inner London - three Jubilee Line trains wait at the Stratford terminus in 2016.
Etymology
Probably named after the shape of the tunnels; the Tube is an informal name for London Underground which has been trademarked.
Noun
tube train (plural tube trains)
- (rail transport, Britain) A smaller-profile underground train which operates through the tube tunnels under London, which have a small cross section.
Usage notes
Tube trains are operated on the Bakerloo, Central, Jubilee, Northern, Piccadilly, Victoria and Waterloo & City Lines. The trains that operate on the Circle, District, Hammersmith & City and Metropolitan Lines pass through larger tunnels and accordingly have a larger profile; these should be called underground trains, not "tube trains".
