Proposals for Old Oak Common being considered by Transport for London include a scheme to realign the routes of both the West London and North London lines around the Old Oak Common site to create a new London Overground interchange station. The proposal envisages diverting the NLL Richmond route to curve around the eastern side of Old Oak Common, and re-routing the WLL to branch west south of the Mitre Bridge before curving north along a short section of the Dudding Hill Line to join the West Coast Main Line. The NLL and WLL would meet at a point on the southern side of Old Oak Common, adjacent to Wormwood Scrubs, where new interchange platforms would be built. Alternative versions of this scheme also consider cheaper options such as terminating the WLL at Old Oak Common or two separate London Overground stations.
