Concessionary fares on the British railway network

In addition to the large number and variety of short-term or localised promotional fares that have been available to passengers on the British railway network in recent decades (especially since privatisation), there are many permanent concessionary fare schemes available to passengers. Some of these take the form of Railcards, which can be purchased by people who qualify according to the conditions, and which give discounts for all journeys over a period; other concessions are available for individual journeys.
