944.This paragraph sets out the procedure to be followed by the Secretary of State in respect of an operator of a regulated rail vehicle which appears not to comply with the construction requirements of rail vehicle accessibility regulations. The procedure would involve the issue of “improvement” and “final” notices and, if the vehicle is used despite still being non-compliant with those elements of rail vehicle accessibility regulations with which it is required to conform, the Secretary of State could impose a penalty. The various timescales leading up to the imposition of the penalty would have to be set out in regulations.
