Commuters are concerned that fast services might be cut

A spokesman said the Swindon-based company would look at all comments, suggestions and requests and assess which changes could be made.

But a spokesman for the Severnside Community Rail Partnership said he feared a reduction in rolling stock.

"We are pressing FGW to re-consider the approach to rolling stock," he said.

Finalised timetable

Alison Forster, Managing Director of First Great Western, said: "We can only operate additional services, over and above those in the Department for Transport's specification, if services are commercially viable.

"We won't be able to accommodate every suggestion but we do promise to look at all the feedback we have received and make changes where they are possible."

Any revised timetable will need to be approved by the Department for Transport, Network Rail and industry partners including other train operators.

The finalised timetable will be introduced early in December 2006.
