Article 3 Exemption
Subject to paragraphs 2 and 3 a MS exempt vehicle is authorised to be used for carriage on the Metropolitan Line even if it is used in a manner that does not conform with the requirements of paragraph 1(1) (boarding devices at wheelchair compatible doorways), but only in so far as the vehicle is stationary at a station platform named in a table in the Schedule.
The exemption from paragraph 1(1) expires—
in relation to a station platform named in table 1 in the Schedule, at the end of the day indicated against its name;
in relation to a station platform named in table 2 in the Schedule, when step-free access is provided to that station platform;
in relation to a station platform named in table 3 in the Schedule, at the earlier of the dates—
when that platform can safely be accessed by a disabled person using a wheelchair from a pre-1999 vehicle which is providing a service on the Piccadilly Line at that station; or
when step-free access is provided to all platforms at that station.
The exemption from paragraph 1(1) does not expire in relation to a station platform named in table 4 in the Schedule.
