Stratford International station

High Speed 1 station concourse

The station is on the High Speed 1 railway between St. Pancras and Ebbsfleet International. As the station lies just inside the eastern boundary of the London Olympic Park, much of the surrounding land was little more than a construction site until mid-2012.[9]

The tracks descend into tunnel at both ends of the station as its platforms are closer to the surface than the tunnels; some of the platforms have a noticeable dip along their length at the east end. Stratford International has four platforms in the station box: two at the outer edges and two shorter ones forming a central island. The main line through tracks run down each side of the station between the adjacent platforms. There is a waiting room on the island platforms but not on the outer platforms.

35 metres beyond the eastern portals, the tunnels pass just below the Central line tunnels curving north from Stratford. The bottom invert of each Central line tunnel is only 4.3 metres (14 ft) and 8.0 metres (26 ft) above the high-speed running tunnels.[8]^:153–156

The station was not authorised by the Channel Tunnel Rail Link Act 1996 and an order under the Transport and Works Act 1992 had to be made to allow for its construction.[10] In the centre of the station is a single-track inclined viaduct, rising to the east end along and above the length of the island platforms. This is to allow out-of-service trains to leave the station box and reach the depot at Temple Mills.

The original intended purpose of Stratford International station was to act as the London stop for regional Eurostar trains bypassing St Pancras and continuing to other destinations in Britain.[15] However, these services did not come into being, and Rob Holden, chief executive of LCR and deputy chairman of Eurostar, stated that, "stopping a high-speed train seven minutes out of St Pancras is less than ideal", leaving only the domestic Southeastern trains serving the station.[15] Critics derided the station as a white elephant.[16]

By the time Southeastern was serving the station, the Transport Secretary Lord Adonis was urged by Sir Robin Wales, former Mayor of Newham, and Peter Miller, Westfield Stratford City's CEO, to order Eurostar to stop at the station.[17] John Burton, development director of Westfield's Stratford City mall, said domestic services were a "poor substitute" for Eurostar: "International commuters are essential in order to realise the vision of a major metropolitan centre for east London. Direct international services will be a key part of the legacy of the Olympics."[16]

Miller and local politicians including former Mayor Ken Livingstone warned that international services would be vital for the success of the Stratford City scheme and the regeneration of East London.[15][17] London Assembly member Andrew Boff has suggested that rail operators considering running international trains should be forced to stop at Stratford International as part of their High Speed 1 line access.[18] However, Eurostar could not stop during the 2012 London Olympics[19] because of the high frequency of the Javelin service.

There are several other potential operators that may use the station for International services including Deutsche Bahn's proposed London-Frankfurt service.[20]

Access to the station was, at design stage, to be via a new link road to Waterden Road, which linked in turn to the A12 at Lea Interchange and south to Carpenters Road. This link road was constructed and a new signal junction installed on Waterden Road but never opened. However, these roads were stopped up in mid-2007 to enable the construction of the Olympic Park.

When opened it was located adjacent to the construction sites of both the London Olympic Park and Westfield Stratford City shopping centre which prevented pedestrian access; during local redevelopment work a temporary bus service linked Stratford International to nearby Stratford. The DLR station opened on 31 August 2011,[21] and Westfield Stratford City on 13 September 2011.[22] The bus service ran until 20 September.[23]
