The British Rail Class 92 is a dual-voltage electric locomotive, which can run on 25 kV AC from overhead wires or 750 V DC from a third rail. It was designed specifically to operate services through the Channel Tunnel between Great Britain and France. Eurotunnel indicates the Class 92 locomotive as the reference for other locomotives which railway undertakings might want to get certified for usage in the Channel tunnel.

Locomotives of this type are operated by GB Railfreight/Europorte 2 and DB Cargo UK. In France, a number were also owned and operated by SNCF; these were classified as CC 92000 on French railways.

The Class 92 was intended as a mixed-traffic locomotive both for hauling international freight trains and the ill-fated, never introduced Nightstar passenger sleeper trains though the Channel Tunnel. Since introduction, the fleet was exclusively allocated to freight; however, in March 2015, six locomotives owned by GB Railfreight have begun passenger operations hauling the Caledonian Sleeper on behalf of Serco between London and Scotland, marking the first use of the class in commercial passenger service.
