Eurostar said there was nothing âtechnicallyâ to stop that limit being raised to 200mph once the new trains come into service.

A French high-speed train (TGV) has smashed the world record for a train on conventional rails by a big margin, reaching 574.8km/h (356mph). The previous TGV record was 515km/h (320mph), set in 1990. The record attempt by a modified TGV took place on a track between Paris and the eastern city of Strasbourg. The absolute train speed record was set by a Japanese magnetic levitation train - Maglev - in 2003. It reached a top speed of 581km/h (361mph). The TGV set the new record at 1314 (1114GMT) on Tuesday. It was a modified version called V150, with larger wheels than usual and two engines driving three double-decker cars.
