Tickets for the maiden Eurostar departures from its new home at St Pancras International have today gone on sale for the first time.
Travellers can also buy tickets for the final journeys made from Waterloo International to continental Europe that will depart on the evening of November 13th this year.
In what Eurostar says is an "unprecedented" move, services will then switch overnight to leave from their new home at St Pancras on the following day, ending 13 years of association with Waterloo
The vacant platforms at the station, which serves the south, are due to be converted for use by commuter trains.
Trains leaving from St Pancras will be able to reach speeds of 186mph on a specially-designed high-speed line, which will also link up with existing station Ashford International and new facility Ebbsfleet International in Kent.
According to Eurostar the move to St Pancras will open up high-speed rail services to millions of Britons, with seven mainline train companies operating through St Pancras, King's Cross and nearby Euston, as well as six London Underground lines.
"We are expecting heavy demand from customers keen to enjoy even faster, shorter journeys to the continent, and who want to see the stunning restoration of St Pancras International station," commented Richard Brown, chief executive of the rail firm.
"I'm sure that many people will also want to travel on the final Eurostar services from Waterloo, joining us in saying 'goodbye' to our old London home."
According to Eurostar, its trains emit ten times less carbon dioxide than comparable journeys by air.
