Harsh winter conditions damaged part of the narrow gauge railway, which runs for 2.25 miles between Heatherslaw and Etal.
Paul Smith, managing director, said: “The railway opened on Sunday after a pretty brutal winter’s work.
“We have been re-laying sections of track again and although the big snow held us up for a while we managed to finish off most of the work we set out to complete. We are hoping for a busy Easter and that the weather behaves itself from now on.
“Moving forward we will be renovating the next coach throughout the year having completed and returned another one back into service after the winter. Always more work to do!”
Meanwhile, visitors to the Heatherslaw Light Railway will now be able to take a look into a local illustrator’s working studio.
Imogen Aitchison of Imogen Louise Design has a new home in the antique caravan at Heatherslaw station.
Inspired by the surrounding countryside, Imogen, a graduate from the Glasgow School of Art, will be creating and selling a range of wildlife and farming based designs and gifts from her new studio.
Visitors to Heatherslaw Station will be welcome to explore the studio and discover more about the design process involved and view fine examples of her finished work.
