The train operator Northern has been criticised for prosecuting young people, leaving some facing bills of hundreds of pounds, after they have used their railcards to save just a few pounds on morning journeys.
Restrictions on a 16-25 railcard, which can also be bought by full-time students, mean that discounts can only be applied to an “anytime” ticket before 10am if the fare is £12 or more, requiring cardholders to pay full fare for cheaper tickets.
