Southeastern high-speed trains

Whether you're travelling for work, leisure or a bit of both Southeastern's high-speed services get you to your destination quickly and in the most convenient way.

Southeastern trains introduced a high-speed train timetable in 2009, using the HS1 line to connect St Pancras with Ashford and Ebbsfleet International with a domestic route.

These new high-speed rail routes allowed passengers to reach the capital in just 38 minutes from Ashford. When travelling on Southeastern’s high-speed line, there will be a surcharge to use the line. However, there are still chances to get a discount on your journey, using all network railcards to get cheaper tickets to London at twice the speed!

There is also the opportunity to use an oyster card between St Pancras and Stratford International, which will cost less than a standard high-speed ticket between the stations.
