Eurostar / British Rail / SNCF / NMBS

'Eurostar / British Rail / SNCF / NMBS' is used in this encyclopedia for the international high-speed passenger railway operating through the Channel Tunnel from 14 November 1994. Eurostar was originally a joint operation of European Passenger Services (a British Rail subsidiary, later Eurostar UK Ltd), SNCF (France) and NMBS/SNCB (Belgium).

The original Class 373 'TransManche Super Train' of 1993 (a tri-voltage, 18- or 20-car version of the French TGV designed for Channel Tunnel through-running) operated the original London Waterloo–Paris/Brussels services until 2007, when High Speed 1 opened and operations transferred to St Pancras International. The Class 373 was joined and progressively replaced by the Class 374 'e320' (Siemens Velaro) from 2015.

Eurostar was reorganised as a single private company in 2010 and acquired Thalys (the Paris–Brussels–Cologne–Amsterdam high-speed operator) in 2024 to form the unified 'Eurostar' brand across both networks.
