Modernisation
From 1999 onwards, the then ScotRail owner, National Express, began the removal of the Class 156 "Sprinter" trains. Their replacement was to be the faster, higher standard Class 158. These trains offered a better all round travelling experience, with air conditioning, improved speed, lighting, seating, storage and general comfort. There is now a dedicated fleet of Class 158 units based at Inverness serving the Kyle of Lochalsh line (also serving the Far North Line to Wick and Thurso and Aberdeen to Inverness Line to Aberdeen). The current franchise owner First ScotRail has continued the current situation, with improvement to the depot facilities at Inverness.
