London Underground 1900 and 1903 Stock
It was found that conversion to electric multiple units solved the problem, so new motor cars were bought and replaced all the locomotives by June 1903.These arrived in 1915, but completion of the extension was delayed due to the outbreak of World War I, and the cars were stored.In 1925–1928 the trains were reconstructed, replacing the gated ends with air-operated doors, allowing the number of guards to be reduced to two.The Board of Trade appointed an investigating committee in January 1901, which reported in May that the problem was due to the large unsprung mass of the 44-ton locomotives, and the track.[5] The following month, after four of the carriages had been converted into motor cars and fitted with British Thomson-Houston control equipment that had been invented by Frank J. Sprague in Chicago, an electric multiple unit was tested.In 1911 there was agreement to connect the line to the Central London Railway and for the CLR to run trains to Ealing.From 1923 Standard Stock operated on the Hampstead line, allowing staff to be reduced to front and rear guards and a driver.[19] The end platforms were enclosed and trailer cars were equipped with two 3 feet 6 inches (1.07 m) openings with a single leaf sliding doors on each side.[18] The sliding doors were pneumatically operated, later assisted with electrically controlled exhaust valves to speed up opening.
