Can I use my Railcard for tickets for travel on the London Underground?
When you buy discounted rail tickets using your Railcard for London mainline train stations, they are valid for use on the London Underground if you need to use the tube to get to the mainline train station. Off-Peak Day Travelcards (All Zones only) are also available, subject to a minimum fare. However, we’re sorry that you can’t use your Railcard to get a discount when buying tickets from a London Underground booking office. If you have an Oyster pay as you go card, you can get your Railcard discount loaded onto your Oyster card to save 1/3 on the daily fare cap.
