OUR Locomotives
37403 ‘Isle of mull’
37403 (D6607/37307) was the penultimate of 309 English Electric Type 3s, Class 37, to be built at Vulcan Foundry, Newton-le-Willows, entering service in South Wales as D6607 in October 1965.
In 1984 the locomotive was selected for life extension work at Crewe Works where it was overhauled and fitted with ETH (Electric Train Heating) for use on passenger trains in Scotland. 37403 was released into traffic following overhaul on the 26th June 1985 along with sister locomotive 37401 ‘Mary Queen of Scots’, which is now owned by our partners at Locomotive Services Ltd.
The locomotive was based at Eastfield depot in Glasgow and spent most of its life operating along the West Highland Line to Oban, Fort William and Mallaig before being replaced by more modern sprinter trains in 1989.
37403 was stored in 2000 and remained stored until it was saved for preservation in 2008, firstly by BRE Ltd and then the Scottish Railway Preservation Society at Bo’ness. The locomotive arrived at Bo’ness during November 2008 for one of the biggest overhauls undertaken by our diesel group to return the locomotive to mainline condition.
In 2016, 37403, sporting the smart Large Logo livery and carrying the name ‘Isle of Mull’ was released back into mainline service. From 2016 until 2020 the locomotive was hired out to Direct Rail Services before returning to Bo’ness for a light overhaul. In 2022, 37403 returned to the mainline again and has since been seen around the United Kingdom at the front of Railtours and has even hauled the Caledonian Sleeper services in 2024 and 2025! The locomotive has proved itself to be a valuable asset due to its reliability and powerful performances.
37025 ‘Inverness TMD’
37025 (D6725) was built at Vulcan Foundry, Newton-Le-Willows, and released into traffic on the 31st August 1961, allocated to Stratford Depot in London.
37025 was transferred to the Scottish region in 1981 and would remain a Scottish Locomotive for much of its remaining career at both Eastfield Depot, Glasgow, and Inverness Depot. The locomotive worked along some of Scotland’s most scenic lines including the lines to Inverness, Kyle of Lochalsh and Fort William.
In 1994 37025 was named ‘Inverness TMD’ in a variation of the classic BR Large Logo livery it had carried earlier in its career. It retained its name and livery until storage came in 1998.
In 2000, The Scottish Thirty-Seven Group, based at the Bo'ness & Kinneil Railway, purchased 37025 for preservation. Over a 7 year period, the SRPS diesel group 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 and was renamed 'Inverness TMD'.
On the 18th January 2016, a wonderful moment for the STG and SRPS Diesel Group occurred as 37025 returned to the mainline once again 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.
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. In 2026, 37025, will return to the mainline following an extensive bogie overhaul and will once again be seen at the front of an SRPS Railtour!
