Inaccurate for wheelchair users to rely on as it honestly doesn't pick up wheelchair accessible stations for example from London Waterloo gives you play form 3 at Raynes Park there is no wheelchair access off station on platforms 3 or 4. You would have to go down to New Malden Change platforms and come in on 1 or 2. Alternatively disembark at Wimbledon and use the bus if the ramps working or space!
