a new signal box was provided. In 1905 the platforms were extended and the station was repainted the following year. In 1907 a short siding on the up side south of the station to a ballast pit operated by Boyer & Son was opened. Expansion of the horticultural industry saw the goods yard extended in 1909. Inwards traffic was manure and coal for the horticultural industry. Falling passenger numbers saw the Churchbury Loop passenger services withdrawn on 1 October 1909 and the then President of the Board of Trade, Winston Churchill, had to answer a question on the subject in the House of Commons as a railway closure was, at that point, a rare occurrence. During World War I the Lea Valley was a centre of the munitions industry and the government called on the GER to restore passenger services which served the original stations. but once the war finished demand again fell off and services were withdrawn on 1 July 1919. London & North Eastern Railway (1923-1947) On 1 January 1923 the GER became part of the London & North Eastern Railway. In 1932 a new down loop was added south of the junction for the Churchbury Loop line. At this stage the signal box which was located south of the station on the up side had 63 levers for the operation of points and signals. British Railways (1948-1996) The nationalisation of Britain's railways saw the operation of Cheshunt station pass to British Railways Eastern Region. from 1958 local passenger services between Cheshunt and London via Tottenham Hale were normally operated by Class 125 diesel multiple units. The lines from via Seven Sisters to and , including those through Cheshunt, were electrified on 21 November 1960. This saw the restoration of passenger services to the former Churchbury Loop line which was renamed the Southbury Loop. Because the Lea Valley local services were diesel operated the down side bay where these normally terminated was not electrified. The goods yard was closed on 1 June 1966. In preparation for the new Lea Valley electric services the area was re-signalled on 11/12 January 1969 although Cheshunt signal box was retained. The lines south via were not electrified until 10 March the same year with electric passenger services starting on 5 May 1969. When sectorisation was introduced in the 1980s, the station was served by Network SouthEast until the privatisation of British Railways.
