ScotRail Alliance has announced it's increasing the number of train journeys between Carlisle and Dumfries.
Passengers will benefit from an extra 1,500 seats per day on an extra five services, in each direction, from Sunday 10 December.
There will also be new early morning trains from Dumfries to Glasgow, and a late return service, providing 300 more seats between the stations.
The improvements mean customers in the south west of Scotland will see close to an hourly service throughout the day.
