 In the early 1960s yellow warning panels, now characteristic of British railways, were added to the fronts of diesel and electric locomotives and multiple units in order to increase the safety of track workers.The Transport Act 1962 converted British Railways from being the trade name of a BTC activity to a separate public corporation, as the British Railways Board.As the last steam locomotives were withdrawn, the corporation's public name was re-branded in 1965 as British Rail (see British Rail brand names for a full history).
