And train users are being asked to avoid travel over the weekend as the Rail, Maritime and Transport Union (RMT) members take strike action.
There will be major disruption to TransPennine Express (TPE) services that serve Dumfriesshire on both Saturday and Sunday, and customers are being urged to travel either side of the weekend instead.
The rail operator will only be running a very small number of services during this time and anyone making an essential journey should plan ahead, check very carefully and allow extra time when travelling as trains will be very busy and changes and cancellations are likely.
Network Rail will also be carrying out major engineering work across the weekend, including on Bank Holiday Monday, which will mean fewer trains and some bus replacements will be in place.
