Passengers in Brentford have now been waiting more than six months for a bus route to be fully reinstated, with transport chiefs blamed for the latest "stalemate".

The 235 route between Sunbury and Brentford has been cut short since May this year, with campaigners claiming many elderly and disabled passengers have been left stranded as a result.

The route is meant to terminate at the Great West Quarter (GWQ), in Ealing Road, Brentford, but a broken bollard there meant buses were unable to serve the estate and have instead been making their last stop outside Brentford County Court, in the High Street.

Barratt London, which manages the estate, says the necessary repairs have now been carried out, but there is no word yet from Transport for London (TfL) as to when the route will be restored to its full length.

Hounslow Council leader Steve Curran this week blamed London Buses (a subsidiary of TfL) for the latest "impasse".

"Hounslow Council has facilitated meetings between Barratt and TfL to ensure the return of the 235 bus in to the GWQ.

"An agreement was reached which will formalise the use of the central Piazza for buses but we have reached a new impasse in the form of London Buses, whose management are prevaricating for reasons which aren't clear."

Mr Curran said he had now written to Isabel Dedring, the mayor of London's deputy mayor for transport, asking for her help to resolve the "stalemate", which he said had "greatly inconvenienced" many residents.

Martin Webb, who has campaigned for the route to be reinstated, said he and other passengers were growingly increasingly frustated at the wait.

"It is now three months since we were assured the 235 would be reinstated to serve the GWQ yet the only update is via the website londonbusroutes.net, which shows it will be restored on December 1," he said.

"As this is about the sixth update and there is still no sign of anything being done I doubt this means very much."

Peter Bradley, TfL's head of consultation, said: "We apologise to route 235 passengers for the continued disruption to their journeys. We are working with Hounslow Council and Barratt to return the route 235 bus service to the GWQ as soon as possible."

A spokeswoman for Barratt London said: "The necessary repairs have been made and we are in discussions with the various parties involved as to when service will resume."
