The Railway and Canal Traffic Acts also saddled BR with the necessity to maintain thousands of goods yards and other facilities, plus rolling stock and staff to service them, even when there was ever-decreasing demand for those services and such traffic as did exist was rarely profitable. This issue had been identified during the Great Depression, and the Big Four had campaigned for repeal of the Railway and Canal Traffic Acts as a 'Fair Deal' during the 1930s. However, this did not happen until the Transport Act 1962 gave BR freedom of contract, and until then the Modernisation Plan had to commission locomotives, rolling stock and facilities to manage the ever-declining but legally-required wagonload freight traffic.
