Since 14 November 2007, all Eurostar trains have been routed via High Speed 1 to or from the redeveloped London terminus at St Pancras International, which at a cost of £800 million was extensively rebuilt and extended to cope with 394-metre (431 yd) long Eurostar trains.[13][84][85] It had been intended to retain some Eurostar services at Waterloo International, but this was ruled out on cost grounds.[86] Completion of High Speed 1 has increased the potential number of trains serving London.
