The station has 11 platforms. Platforms 1–4 are for London Underground, platforms 5 and 8 are for inner suburban South Western Railway services, platform 9 is for Thameslink and platforms 10a and 10b are for Tramlink. Platforms 6 and 7 are adjacent to the fast tracks intended for express and outer suburban South Western Railway services, but most of these services only call at Wimbledon during the Wimbledon Tennis Championships. Access to these platforms is via sliding gates through safety fencing installed in March 2014.
