Class 126 (4 vehicles)
The Class 126 fleet has a troubled history but thankfully a happy ending. These 3-car sets were built by Swindon and always containing blue asbestos, their preservation status was for some time unstable.
Initially, only buffet cars were preserved with the North Yorkshire Moors Railway taking three and the Strathspey Railway one during the 1970's.
The early 1980's saw the surviving Class 126 fleet disposed of. Luckily, the Swindon Diesel Preservation Society recognised the historical importance of the Class 126 (they ran for their whole lives in Scotland) and preserved a full (correct formation) DMBS-TCL-DMSL three car set, which included a pair of unique powercars.
By the 1990's all of the buffet cars preserved twenty years previously were scrapped due to their asbestos contamination, a single example (of the earlier "Edinburgh Glasgow" fleet which were very simnilar to Class 126's) surviving and joining the 3-car set as an example of a now unique buffet vehicle.
However these four survivors have also required huge resources to secure their future, not least the costly stripping of the asbestos.
The 3-car set received substantial lottery grant funding which secured their future. They were rebuilt to immaculate standards and now have a secure future in operational condition at the Bo'ness & Kinneil Railway under the ownership of the Scottish Railway Preservation Society. The final (buffet) vehicle has also been asbestos stripped and is currently being rebuilt to an equally high standard.
