To provide additional capacity for Sutton trains on the DR's Wimbledon branch, the DR published a bill on 21 November 1911 seeking permission to construct additional tracks on the L&SWR owned section from Wimbledon to East Putney. The works were approved by the Metropolitan District Railway Act, 1912, which received assent on 7 August 1912. The L&SWR was to build the additional tracks with the DR covering the cost. On 22 November 1912, both the W&SR and the DR published notices that further bills would be submitted to extend the time limit imposed by the 1910 Act for the compulsory purchase of the land needed for the railway, to enable the W&SR to raise additional capital, and to give the DR powers to take over the W&SR. The DR bill contained provisions to increase the capacity on the DR-owned section of the Wimbledon branch, by constructing further additional tracks from south of Parsons Green to south of Walham Green station (now Fulham Broadway). The requested extension of time and other powers were granted by the Wimbledon and Sutton Railway Act, 1913, given Royal Assent on 15 August 1913. In December 1912, the original promoters were replaced on the W&SR board by UERL nominees and the shares in the company were transferred to the UERL or its shareholders. In late 1913, changes were made to the track layout at Wimbledon station, including a new platform for use by the W&SR line trains, and land for the junctions with the L&SWR mainline was purchased. On 16 November 1914, after the outbreak of war, the DR gave notice of another bill which sought a further extension of time for land purchases. The DR was also to stand guarantor for the W&SR and to lease the W&SR's undertakings, in effect taking over the W&SR. This was granted under the Metropolitan District Railway Act, 1915 on 24 June 1915. War-time restrictions prevented any construction and so extensions to the earlier acts were granted each year from 1918 to 1922 to give a final date of 26 July 1924 for completion of the compulsory purchase. Revised Plans In November 1922, notices of new bills to be placed before Parliament were published by the W&SR, and by the UERL's subsidiaries the London Electric Railway (LER) and the City and South London Railway (C&SLR, now part of the London Underground's Northern line). Taken together, the bills brought significant
