The first preview train, carrying 400 members of the press and media, was delayed for two hours by technical problems.[5][2][213][214] On 29 May 2002 a Eurostar train was initially sent down a wrong line – towards London Victoria railway station instead of London Waterloo – causing the service to arrive 25 minutes late. A signalling error that led to the incorrect routeing was stated to have caused "no risk" as a result.[215]
