Get 1/3 off train travel for adults and 60% off for kids

With your Railcard you can get 1/3 off Anytime Day Travelcard when bought as part of your journey to London from outside London Zones 1-9 (subject to a minimum fare which is currently £19.10).

Children who turn 16 while your Family & Friends Railcard is valid are still entitled to get a discounted child fare for a time.

If you have a 1-year Family & Friends Railcard, your child who has turned 16 can travel as long as the 1-year Family & Friends Railcard is valid.

If you have a 3-year Family & Friends Railcard, your 16-year old can only travel as a child on the Railcard card until the day before they turn 17.

No. Railcard discounts are available throughout Britain but they are not available on tickets for morning peak period services, for journeys wholly within London & South East Network Railcard area on Mondays to Fridays. (The exceptions to this discounted fare rule are when you travel at weekends and on Public Holidays).
 
The times of morning off-peak services do vary by route and are normally related to the availability of Off Peak  Day tickets. It's best to check with ticket office staff before buying your tickets.

Any adult can buy a Family & Friends Railcard. To use it, at least one of the group travelling must be named on the Railcard and there must also be at least one child travelling on a child rate ticket. The named Railcard holder must travel for the entire journey with any passengers who have been bought discounted tickets.
