Steve and anyone else interested, I have managed to track down 37025's history at
www.scottish37group.co.uk/37025.html
It carried large logo lblue livery and scottie dog but no name from12/1983 to 05/1989. It was then painted railfrieght grey.
In 03/1994 it was named Inverness TMD and returned to large logo Blue livery with Highland Stag Logo. It carried this livery until withdrawn in 1999.
It was then bought by the Scottish Railway Preservation Diesel Group and is being restored at Bo'ness on the Bo'ness and Kinneal Railway.
The engine was fired up last autumn so hopefully it will be in action soon.
