On 1 January 1923 the GER amalgamated with several other railways to form the London and North Eastern Railway (LNER) as a result of the Railways Act 1921, which saw many of the 120 railway companies grouped into four main companies in an effort to stem their losses [REF].
Following the 1947 Transport Act the Big Four railway companies, including the LNER, were amalgamated into the nationalised British Railways (BR).
