NOTES: The Post Office (London) Railway Bill was passed by a Select Committee of the House of Lords in 1913 which reccommended the construction of an electric railway with driverless trains to connect the West and East ends of London. Construction of the tunnels began in 1914 and was completed in 1917. The operating equipment was not installed until after World War I and the railway finally opened on 5 December 1927 with parcels traffic running between Paddington and Mount Pleasant. The line was extended to Liverpool Street on 2 January 1928.
NOTES: Designed as the Festival of Britain's travelling exhibition, 'The Land' visited Leeds, Birmingham and Nottingham between May and October 1951. The exhibition's themes were similar to those of the main site in London but with greater emphasis placed on industrial design.
