Young adults, families, seniors, and couples can get 1/3 off all trains with a £30 railcard
British train tickets are already discounted 50% to children aged 5 to 15 (kids under 5 are free).
Anyone aged 16–25, over 60, couples, families, and the disabled can buy a £30 railcard (£20 for the handicapped) that will get you 33% off all train tickets for one year.
(Sorry, middle-aged singletons; closest you can get is a Network railcard only good in the Southeast region.)
Most are good on Standard and First Class Anytime, and on Off-Peak and Advanced fares (basically, anything after 9:30am on a weekday, plus weekends).
- Two Together Railcard (Twotogether-railcard.co.uk) - For two people over aged 16 traveling together (so really just £15 per person—making it a better deal for than the next one if you are young and have a friend).
- 16-25 Railcard (16-25railcard.co.uk) - For that age range (or a mature student over 25 with proof of student status)
- Family & Friends Railcard (Familyandfriends-railcard.co.uk) - Good for up to four adults and four children (the adults get 1/3 off, the kids 60% off). You can have two adults named on the card, one of whom must be traveling when you use it (along with at least one child).
- Senior Railcard (Senior-railcard.co.uk)
- Disabled Persons Railcard (Disabledpersons-railcard.co.uk) - This one is discounted at £20, and covers the handicapped traveler plus one other adult traveling with him or her.
- Network Railcard (Network-railcard.co.uk) Anyone can get this one, but it only covers Southeast England (which is still a lot). Peruse the map to see if it might be handy for you.
If you happen to have a U.K. mailing address, you can order one online.
