Scotrail have just announced the return of Club 55 for the period 14 May to 30 June 2012. Return travel is valid for up to one month from the date of outward travel. All you need to do is produce proof of age (document, not behaviour . . . ).

Although it's strictly speaking for travel within Scotland, you can also travel to and from Carlisle and Berwick-upon-Tweed to any Scottish destination.
