To travel on high speed services, you can buy walk up or supplement tickets.
Walk up Tickets
Walk up high speed tickets will allow you to travel on high speed services, and can be bought online or at the ticket office.
Supplements
If you have a ticket to London Terminals, a Travelcard ticket or you hold a Season ticket, you can upgrade to high speed services by paying a supplement in addition to your current ticket.
For example, a ticket from Margate to St Pancras International would require a supplement in order to travel on the high speed service between Ashford and St Pancras International.
Supplements cannot be bought online but can be purchased at the ticket office or from any self-service machine*.
Ticket Descriptions
The following ticket descriptions entitle you to travel on high speed services:
PLUS HIGH SPEED – this is shown on either a walk up or supplement ticket.

Passengers holding a valid first class ticket may be entitled to travel on high speed services free of charge. Ask at your local station whether your ticket entitles you to use high speed services.
Tickets to or from London which display the 'Any Permitted' route do not entitle you to travel on high speed services.
Railcard discounts apply.
