 There is no restriction on the number of times the Railcard can be used to purchase discounted tickets during the period of its validity, and there are no geographical restrictions on its use.Introduced in 1974 on an experimental basis, under the name Student Card, and expanded into the Student Railcard later that year, it was the first of the many Railcards which formed part of British Rail's array of concessionary fare schemes, and which still exist on the post-privatisation railway network.Later, it was rebranded as the Young Persons Railcard and, from 18 May 2008, the 16–25 Railcard.
