We're on the Highspeed London-Ashford Route. Starting on London St. Pancras International We are on St. Pancras, with many long platforms used by Eurostar, Southeastern Highspeed, East Midlands Railway and a little bit of Thameslink. This station is the most beautiful, used of service and longest of the Route. And Safety Systems on This Station are used of KVB from the French Safety Systems (For Eurostar and Southeastern Highspeed) and AWS (For East Midlands Railway and Thameslink) This Station could be Used for routes: (EMR) To Nottingham / Leeds and others (SEHS) To Faversham / Maidstone West / Margate and others (Eurostar) To Paris / Brussels and others (Thameslink) To Bedford / Brighton and others We are now moving to Stratford International We are on Stratford International, with 4 platforms, the Eurostar will not stop at that station. However, the station is being used by Southeastern Highspeed, and the Safety Systems are only used by TVM. The station seems to have 7 rails in total: 4 Stopper (SEHS), 2 Non-stopper (SEHS, Eurostar) , 1 Eurostar Use (Eurostar). We are now moving to Ebbsfleet International We are on Ebbsfleet International, where the TVM ends, starts and continues and where AWS starts and ends. This station is both for Eurostar and Southeastern Highspeed. Eurostar can go non-stopper and stopper on this station but the Southeastern Highspeed will only do stopper. Must note that in likely a mile, the Eurostar will receive a 300 km/h speed limit after passing Ebbsfleet International. We are now moving to Ashford International We are on Ashford International, where this route ends, but for both of the services Eurostar will continue and Southeastern Highspeed will continue or end. Eurostar will still be able to do a non-stop or stop the station. As it is for SEHS Class 395 to change from 25kV AC to 750V DC to continue. This station is also used by Southern on route to Eastbourne.
