A Traffic boss has pledged to investigate allegations that a bus firm is operating unreliable services - but he can do so only if passengers make a formal complaint.

Traffic Commissioner Keith Waterworth has urged people to inform him of problems they have experienced with Stagecoach Ribble since it took over privatised bus operations in Hyndburn, Ribble Valley and Burnley.

The move comes as Stagecoach's Manchester operation defends its record of service provision and bus maintenance, at a public inquiry in Leeds.

The hearing was instigated by the Traffic Commissioner because of the number of buses which the company has had to take off the road for repairs and the number of complaints received from the public.

Mr Waterworth, who is based in Leeds but covers the North West area, has the power to suspend a bus operator's licence and reduce the number of vehicles it can operate if he thinks action is justified. Scores of passengers have complained about the standard of service offered by Stagecoach on timetabled routes.

Schools in Hyndburn and Ribble Valley fear pupils may miss exams because of problems with schools services.

Although the Traffic Commissioner does not oversee separate schools contracts, he does have jurisdiction over safety standards on all buses.

Last week, Stagecaoch Ribble apologised for the problems and blamed a shortage of drivers, saying ten had resigned following the closure of the Accrington bus depot.

A spokesman for the Traffic Commissioner revealed that only a couple of complaints had been received about the Stagecoach Ribble operation.

He added: "Unless people complain officially then we can't investigate.

"People who experience difficulties with the service should first complain to Stagecoach Ribble and, if they are not satisfied they should refer the matter to the Traffic Commissioner.

"He will investigate their complaints and take the action he feels is necessary."
