His reply is doubly disappointing for those campaigning for the introduction of a Piccadilly Line service as it appears to rule out any possibility of the service being introduced in the foreseeable future. The Mayor repeats familiar arguments about timetabling and signalling constraints and concludes "There is therefore little opportunity to extend the times that the Piccadilly Line trains stop at Turnham Green."

Following the Mayor of London’s refusal Cllr Ruth Cadbury, Hounslow’s Executive Member for Enhancing Our Environment, said: “We are disappointed at this decision as we were encouraging commuters and other travellers to use tube and train services during the closure, and making Turnham Green station more accessible might have reduced the inevitable road traffic congestion in the area."

She added that the lower usage of the tube over the Summer period would have been an ideal opportunity to pilot the service. The Council will continue to press the Mayor on this issue.

One local resident who has campaigned for a Piccadilly Line tube service for over 10 years said, "The really disappointing thing about this is that the Mayor's letter makes no mention of the review that was promised previously. It reads like another stock missive from London Underground's customer services department who clearly drafted it on the Mayor's behalf. Has the champion of public transport become yet another 'dunderhead'?"
