I've been with Natwest for a year (adapt account 18 and under), they've upgrade me to a student account. They said they no longer do railcards regardless of when you set up the account.
However you do receive a free 'Taste Membership' card which gives you 50% off at lots of restaurants e.g. Pizza Express, GBK, ASK, Strada. I'd much rather prefer the railcard but cba to change
