Scottish Thirty-Seven Group, Edinburgh (2026)

Our group, 'The Scottish Thirty-seven Group', came into existence in 1997 formed by a handful of Scottish Railway Preservationists to buy and operate a Class 37 locomotive in Scotland. Based at the Bo'ness & Kinneil Railway, over 7 years, we have stripped down, repaired and painstakingly restored 025 back into a serviceable status. On 27 September 2007, 37025 complete in BR large logo blue livery

worked its first train in over 8 years. Since then, 'Inverness TMD' has been a stalwart of Bo'ness diesel engine fleet with many appearances on passenger and freight trains on the railway. In June 2009, 37025 ventured to foreign metals and the Keighley and Worth Valley Railway. In October 2010, it was one of the exhibits at the National Railway Museum's class 37 50th anniversary event. On the 18th January 2016, a wonderful moment for the group and the SRPS Diesel Group occurred as 37025 returned to the mainline after many hours of hard work by all the volunteers at Bo'ness (both STG and SRPS) when it ran light engine from Bo'ness to Washford Heath to begin its career on hire to Colas Rail Freight. Since then the loco has worked regularly for Colas Rail travelling all over the United Kingdom hauling various Network Rail test trains. On the 16th July 2016, 37025 hauled its first railtour since returning to the mainline when it was in charge of SRPS Railtours 'The Golden Stag' running from Linlithgow to Inverness and return. Since then 37025 has gone on to work other SRPS Railtours including a trip to Wick and Thurso with 37421 which included 37025 providing steam heat supply to the coaches. Our second loco 37261 'Caithness' arrived at Bo'ness from Barrow Hill following withdrawal by DRS on the 13th July 2015 and is now subject to a full rebuild and overhaul to running condition. Regular updates on progress will be posted on this page. Our third loco is 37214 which arrived at Bo'ness from Carnforth on the 22nd September 2017 and is currently providing valuable spares to both 37025 and 37261.
