The Olympic Javelin is a planned high-speed train shuttle service announced as part of the successful London 2012 Olympic bid. It is an integral part of the plan to improve public transport in London in readiness for the 2012 Summer Olympics, an area of the bid that was initially regarded as being poor by the International Olympic Committee (IOC).
The service will run for the duration of the games, between St Pancras International station and Ebbsfleet International station, via Stratford International station, which will be situated within the planned Olympic Park. The service is to be operated by Southeastern as part of the domestic services on High Speed 1.
On both legs, the service will run exclusively on tracks of Section 2 of High Speed 1.
It is expected that over 80% of Olympic spectators will travel to and from the venues by rail. Services to the Olympic Park are projected to have a capacity of 240,000 travellers per hour, with around 25,000 of those using the Javelin service.
It is planned that the service will use the same fleet of Class 395 trains as ordered for High Speed 1 domestic commuter services. Domestic services will be suspended during the course of the Olympic Games.
An order worth £250 million has been placed with Hitachi Europe for 29 high speed "A-trains", based on the same technology as the Japanese Shinkansen high-speed trains. These are expected to be in service by 2009, and should reach speeds of 140 mph (225 km/h).
