<P> The terminus for the high - speed line in London is St Pancras railway station . During the 2000s, towards the end of the construction of the CTRL, the entire station complex was renovated, expanded and rebranded as St Pancras International, with a new security - sealed terminal area for Eurostar trains to continental Europe . In addition, it retained traditional domestic connections to the north and south of England . The new extension doubled the length of the central platforms now used for Eurostar services; new platforms have been provided for existing domestic East Midlands Trains and the Southeastern high - speed services that run along High Speed 1 to Kent . New platforms on the Thameslink line across London were built beneath the western margins of the station, and the station at King's Cross Thameslink was closed . </P> <P> A complex junction has been built north of St Pancras with connections to the East Coast Main Line, North London Line (for West Coast Main Line) and Midland Main Line, allowing for a wide variety of potential destinations albeit on conventional rails . As part of the works, tunnels connecting the East Coast Main Line to the Thameslink route were also built in readiness for the forthcoming Thameslink Programme . </P> <P> Stratford International railway station was not part of the original government plans for the CTRL . Despite its name, no international services call there . Completed in April 2006, it opened on 30 November 2009 when the domestic preview Southeastern highspeed services started calling there . An extension of the Docklands Light Railway opened to Stratford International in August 2011 . It forms part of the complex of railway stations for the main site where the 2012 Summer Olympics were held . </P> <P> Temple Mills Depot in Leyton is used for storage and servicing of Eurostar trains and off - peak berthing of Class 395 Southeastern high - speed trains . </P>
