The Southeastern highspeed runs between St Pancras International, Stratford International, Ebbsfleet International, and Ashford International. The highspeed Javelin trains will also run into Kent to destinations such as Medway, Whitstable, Maidstone, Canterbury, Folkestone, Dover, and Ramsgate.
If your journey involves you travelling on the highspeed route, your ticket will need to have the Plus High Speed route allowance on it. If you don't have the right ticket, you'll need to travel to or from another of our London Terminals.
If you're travelling on one of our highspeed Javelin trains on the mainlines in Kent, then you won't need the highspeed route allowance unless you also travel between St Pancras, Stratford, Ebbsfleet, or Ashford.
In order to travel on the Southeastern highspeed with a ticket that doesn't have a highspeed allowance, you can buy High Speed Upgrades from ticket machines and ticket offices at Southeastern stations.
If your journey takes you on the highspeed route but you're travelling through London to a destination elsewhere in the UK, then the ticket won't have the highspeed route on it, but will still be allowed. Always check your journey itinerary when buying the ticket.
