Morden is a London Underground station in Morden in the London Borough of Merton. The station is the southern terminus for the Northern line and is the most southerly station on the Underground network, despite being on the Northern Line. The next station towards north is . The station is located on London Road (A24), and is in Travelcard Zone 4. Nearby are Morden Hall Park and Morden Park. The station was one of the first modernist designs produced for the London Underground by Charles Holden. Its opening in 1926 contributed to the rapid development of new suburbs in what was then a rural part of Surrey with the population of the parish increasing nine-fold in the decade 1921–1931. In the period following the end of First World War, the Underground Electric Railways Company of London (UERL) began reviving a series of prewar plans for line extensions and improvements that had been postponed during the hostilities. Finance for the works was made possible by the government's Trade Facilities Act 1921, which, as a means of alleviating unemployment, provided for the Treasury to underwrite the value of loans raised by companies for public works. One of the projects that had been postponed was the Wimbledon and Sutton Railway (W&SR), a plan for a new surface line from Wimbledon to Sutton over which the UERL's District Railway had control. The UERL wished to maximise its use of the government's time-limited financial backing, and, in November 1922, presented bills to parliament to construct the W&SR in conjunction with an extension of the UERL's City and South London Railway (C&SLR) south from through Balham, Tooting and Merton. The C&SLR would connect to the W&SR route south of Morden station and run trains to Sutton and the District Railway would run trains between Wimbledon and Sutton. Under these proposals, the station on the C&SLR extension would have been named "North Morden" and the station on the W&SR route would have been called "South Morden" (the current Morden South station is in a different location).
