Regional Transport and Roads minister Paul Toole has announced the service will start on Monday September 16 departing Bathurst at 7.35am weekdays and returning at 6.47pm.

However, a spokeswoman for NSW Trainlink said a decision had not yet been made on an Orange connection.

"We are still investigating all the options for a connection," she said.

Orange Rail Action Group chairman Dr Peter Bilenkij said they were "very hopeful" the coach link would be provided.

"We believe there should be a connection for the people out of Orange at a reasonable time. It's another opportunity to do business in Sydney," he said.

"Hopefully the coach and Bathurst Bullet 2.0 will be replaced by a new regional train leaving Orange or Dubbo when the new regional fleet is built."

On weekdays the new train will arrive at Sydney's Central station at 11.19am and depart on the return journey at 3.05pm.

TIMETABLE

The existing Bathurst Bullet has a coach connection from Orange at 4.55am, departs Bathurst at 5.46am and arrives in Sydney at 9.27am.

The return service arrives at Bathurst at 9.33pm with a coach connection arriving in Orange at 10.45pm.

Based on those times, if it was provided, a coach connection to the second train would leave Orange about 6.45am.

A return service would arrive in Orange at about 7.35pm-8pm depending on whether it went direct or via Blayney and Millthorpe.

Mr Toole said the second Bullet train would provide passengers with options.

"We know travellers appreciate flexibility and choice when it comes to train travel," he said.

"The new service provides locals with the option of a later start in the morning and an earlier return for those who need to be back for family and social commitments."

It will also stop at Tarana and Rydal which are not stops for the current train.

On weekends it will leave Bathurst at 6.07am and return at 6.52pm, about three hours earlier than the existing Bullet service.
