An improved train service is to operate on the Severn Beach Line in Bristol from next May.
A new Sunday service is being introduced
The current hourly service between the city centre and Severn Beach will be replaced with three trains every two hours on weekdays and Saturdays.
There will also be a new hourly service on Sundays.
Stations along the route will also benefit from £100,000 of investment from Bristol City Council and First Great Western.
Councillor Mark Bradshaw said: "The new, more frequent train service will greatly benefit passengers travelling to and from Bristol from surrounding areas.
"This service improvement will be complemented by the upgrading of stations along the route, making the whole travelling experience much more pleasant."
