The privatisation of British Rail (BR) was the process by which ownership and operation of the railways of Great Britain passed from government control into private hands. Begun in 1994, it had been completed by 1997.
Historically, the British railways had been in state ownership since 1948, with the operating arm BR controlled by the British Railways Board (BRB). Under the Conservative government of Margaret Thatcher elected in 1979, various state-owned businesses were sold off, including various functions related to the railways – Sealink ferries and British Transport Hotels by 1984, Travellers Fare catering by 1988 and British Rail Engineering (train building) by 1989.
It was under Thatcher's successor John Major that the railways themselves were privatised, using the Railways Act 1993. The operations of the BRB were broken up and sold off, with various regulatory functions transferred to the newly created office of the Rail Regulator. Ownership of the infrastructure including the larger stations passed to Railtrack, while track maintenance and renewal assets were sold to 13 companies across the network. Ownership of passenger trains passed to three (ROSCOs) – the stock being leased out to passenger train operating companies (TOCs) awarded contracts through a new system of rail franchising overseen by the Office of Passenger Rail Franchising (OPRAF). Ownership and operation of freight trains passed to two companies – English Welsh & Scottish (EWS) and Freightliner, less than the originally intended six, although there are considerably more now.
