Great British Railways (GBR) is a proposed state-owned public body that is to oversee rail transport in Great Britain except for Transport for London, Merseytravel, light rail and tram services. It is to assume most rail functions of the Department for Transport (DfT) and the Rail Delivery Group, including procuring services and setting fares. In addition, it is to absorb Network Rail to become the operator of most rail infrastructure across Great Britain. It will not affect the existing powers of the UK's devolved administrations in their areas.

The Campaign to Bring Back British Rail is a pressure group in the United Kingdom whose objective is the renationalisation of the British Rail network, which was privatised in the 1990s. In addition to its representation of ordinary passengers, on whose behalf it campaigns for improvements to rail services, it undertakes research for the purpose of lobbying political parties towards the ends of reintroducing a vertically-integrated, publicly owned and operated British railway network. It has over 150,000 supporters UK wide, accumulated since it was founded in 2009, and is managed from two hubs - in Glasgow and London.
