Frustration is growing among "stranded" passengers who have been waiting months for a bus service to resume its full route.

Number 235 buses from Sunbury to Brentford have been terminating outside Brentford County Court since the beginning of May, rather than their usual last call at the Great West Quarter (GWQ) estate in Ealing Road, Brentford.

Angry passengers say the route's curtailment has left many people in the north of Brentford stranded, requiring two buses to reach Hounslow.

Transport for London (TfL) assured customers at the start of July that the service would return to its full route.

But more than a month later there is no indication of when that might happen.

TfL previously said it is waiting for Barratt London, which manages the estate, to repair a broken bollard at GWQ so buses can enter and exit safely. TfL now says it has agreed to fund the repair bill and is waiting for the work to be completed.

A spokeswoman for Barratt London said it remained in discussion with the various parties involved and hoped the situation would be "resolved soon".

A spokeswoman for Hounslow Council, meanwhile, said it was working with Barratt London to fix the damaged rising bollard "as soon as possible".

Jean Nolan, who lives in Springvale Avenue, Brentford is the latest passenger to vent her annoyance at the route's curtailment.

"My husband and I are pensioners and we now have to walk to the bottom of Ealing Road, which is a long way for us, just to catch a bus to Hounslow," she said.

Martin Webb, who uses the 235, pointed out that GWQ developer Barratt Homes paid £620,000 in 2013/14 to cover the cost of extending the service to the estate for the first four years, working out at £155,000 a year.

He asked what would happen to that money, paid to TfL via Hounslow Council, given the length of time for which that extension had been suspended.

A council spokeswoman said it had no plans to recoup any of the funds given to TfL as this was only a "temporary curtailment".

"As the original route has been lengthened, the money has been used to purchase new buses and to recruit additional drivers on a permanent basis," she added.

TfL said the funding had been provided to cover start-up costs of the service, which ran for 18 months before being interrupted, and it would cover the expense once the four years were up.

A Barratt London spokeswoman said any queries regarding the money paid for the service would have to be directed to TfL and the council.
