London Assembly members are to press Mayor Boris Johnson to introduce a 'Passengers Charter' setting out the minimum level of service Tube users can expect.

They say a charter is necessary as Londoners and visitors have "not been given the opportunity to comment" on proposals to close all Tube ticket offices and reduce station staffing levels by 950 posts.

The Assembly welcomed the decision by the RMT and TSSA Unions recently to call off strike action over the issue of ticket offices, and enter talks with Transport for London (TfL).

Labour assembly member Val Shawcross, who proposed the motion, said: "London’s passengers should not be cut out of the debate on ticket offices and staffing reductions and it is wrong of TfL to think it is simply a conversation between them and the Unions. It’s the consumer and democratic right of Londoners to have a say about transport changes that will directly affect them, which is why we believe there should be a station by station consultation with input from the public."

Liberal Democrat AM, Caroline Pidgeon, who seconded the motion, said: "There has been a lot of misinformation from both sides about this issue and as it is a public service there should be a proper public consultation on the matter."

The Assembly urged the Mayor to reflect on his proposals and instruct TfL to conduct a full public consultation, with plans made public for each station affected. They say 19 per cent of tickets are currently sold via ticket offices.

Mike Brown, managing director of London Underground, commented: "We always welcome the feedback, thoughts and ideas of our customers – we listen and act upon such feedback every day. We are undertaking an intensive period of consultation with the unions over the next two months to review our proposals station by station. 

"Following that our customers and stakeholders will be able to see and comment upon our more detailed plans.  In the meantime we will continue to engage with our stakeholders, including London’s Borough councils and many local groups, and to listen carefully to any concerns or issues they raise, as we have been doing continuously since last autumn.”
