Eurostar trains this week reached record speeds of 255km/h during dynamic testing along Channel Tunnel Rail Link (CTRL) section two between Ebbsfleet and St Pancras. 'We started running trains slowly and have built up speed, culminating in tests at 110% of the line speed limit, ' said a spokesman for owners London & Continental Railways.
'We've run trains under London faster than a train has ever been run before - and faster than they're ever likely to run again.' The trip from Ebbsfleet to St Pancras was done in 12 minutes, it is believed.Dynamic testing started this month following completion of static tests in January and February. Junctions between the new line and Network Rail's lines outside St Pancras station, Ebbsfleet and at Ripple Lane near Dagenham are being tested by running short trains over them.
