The Olympic Javelin Train is the planned high speed mode of transport for the millions of expected UK Olympic games spectators, and was announced by the UK Olympic commitee as part of London's successful bid to host the 2012 Olympic Games.  This high speed Javelin Train will be a central part of plans to provide exemplary transport services for the potential 800,000 spectators per day expected to attend the London Olympics. With approximately 7.7 million tickets available for sale and an estimated 1.5 million spectators also expected to watch the 11 day long Paralympic Games, a clean and efficient Olympic travel and transport service is seen as essential to ensure the smooth running of the games.

The high speed Olympic travel service is planned to run between St Pancras station and Ebbsfleet international, via Stratford International situated in the Olympic Park. The Olympic Javelin train service will be run by Southeastern railways.

Three stations - Stratford International, Stratford Regional and West Ham - will be served by 12 lines and are being billed as the three main gateways to the Games.
A frequent "Javelin" train will run from King's Cross station to the Stratford International in seven minutes, carrying up to 25,000 passengers per hour from Central London stations to the Olympic Park. There are plans to carry up to 1200 passengers on each journey of the 6 carriage Javelin Trains.
