Article 4 Exemptions relating to facilities for disabled persons in wheelchairs

Subject to article 6, a wheelchair space vehicle is authorised to be used for carriage on the London Underground, even if it is used in a manner that does not conform with paragraph 1(1) (the boarding device requirement), but only insofar as the vehicle is stationary at a station platform at Turnham Green, or at a station platform named in tables 1, 2 or 3 of Schedule 1.
