I'm hoping Nigel sees this. Is an American citizen traveling in the UK eligible for the Senior Railcard and the concessions that come with it? I am hoping to be in the UK for a couple months next year and this would be a great savings.
I'm an American and I bought the Senior Railcard in the UK twice. I bought them at ticket counters in rail stations. The card is good for a year, as I remember. Your passport will probably be checked. Other concessions are available to all. Just ask.
For eligible journeys you can claim the senior railcard discount before you actually buy the card eg buying one of the cheap advance fares before you arrive in the UK. In those circumstances it means you get a further discount on the already discounted ticket! Just make sure you buy the card when you arrive and have it with you when you get to make the journey.
£28 a year, 1/3 off most journeys. Note - not valid in London and the Southeast M-F before cheap day fares are valid. In other words, not valid in the morning rush. The time that cheap day tickets are valid varies depending on the specific flow.
Thanks all. I was hoping I had understood the rules correctly.
