Scotland's largest privately-owned bus company, McGill's, announced that it has agreed a deal to acquire the Dumbarton-based company for an investment of around £3m.
The acquisition will be complete in December and involves McGill's purchasing the limited entity, buses and Dumbarton depot of Loch Lomond Bus Services Limited, which trades as McColl's.
Ralph Roberts, managing director of McGill's said: "We are delighted to have concluded this deal with McColl's.
"The acquisition fits well with our growth targets and expansion plans for McGill's. From December 10, McGill's will operate all existing McColl's services under the McGill's name.
"The extension of our network to include Alexandria, Balloch, Helensburgh and Clydebank complements our current service provision in West Dunbartonshire."
All 35 existing McColl's staff members will be offered continued employment with McGill's.
Liam McColl, said: "Given the current economic climate, we have decided to focus our efforts on the quality coach hire and school contracts side of our business.
"We believe that the McGill's business model will serve our local passengers well.
"I would like to thank our regular customers for their loyalty over the years."
The Loch Lomond Bus Services Limited takeover is McGill's first since its purchase of Arriva Scotland West in March.
