37403 & 37025 running day

This was a chance to see two Type 3 Class 37s at the Bo'ness and Kinneil Railway on a special running day on the 29th of October 2022 with Type 3 Class 37 CoCo locomotive, British Railways No.37025 (D6725) Inverness TMD & Type 3 Class 37/4 CoCo locomotive, British Railways No.37403 (D6607) Isle of Mull, both restored by SRPS Diesel Group.
Some Class 37025 history:-
Type 3 Class 37 CoCo locomotive, British Railways No.37025 (D6725)
Built by English Electric, Vulcan Foundry, 1961. 1,750 BHP.
The locomotive was delivered new to Stratford depot, London, and was transferred to Glasgow Eastfield in 1981, Inverness in 1982, Eastfield in 1986, Inverness in 1992, Motherwell in 1994, and Bescot in 1995. It was sold for preservation in 2000. Owned by the Scottish 37 Group and restored to full mainline working order renamed Inverness TMD.
Some Class 37403 history:-
Type 3 Class 37/4 CoCo locomotive, British Railways No.37403 (D6607)
Built by English Electric, Vulcan Foundry, 1965. 1,750 BHP.
Named Ben Cruachan, previously Isle of Mull, then Glendarroch.
The locomotive was delivered new to Landore depot, Swansea. It was renumbered 37307 in 1974, and was selected in 1984 as one of twenty five locomotives which were converted to work passenger trains in Scotland. Refurbishment for this role required the replacement of the main generator by an alternator and the provision of electric train heating (ETH). Thus modified as a class 37/4, the locomotive was renumbered 37403, and transferred to Glasgow Eastfield depot. From Eastfield, 37403 worked the West Highland and Oban lines, and was appropriately named Isle of Mull in January 1986. In November 1988, the name was changed to Glendarroch, a fictional place from the then current STV series Take the High Road.

Increasing use of diesel multiple units on passenger trains and declining freight traffic reduced the need for locomotives, and Eastfield depot closed in 1992. 37403 was transferred to Motherwell. It was renamed Ben Cruachan in February 1994, and continued to work the west highland routes. The locomotive was transferred to Toton in 1997 and resumed duties in South Wales. Other than a spell from November 1998 to June 1999 when it returned to Motherwell to haul the ScotRail Fort William sleeper trains, 37403 remained in England and was put into store in 2000. It was subsequently sold to Bedale Railway Engines Ltd. (BREL). SRPS bought the locomotive from the BREL liquidator in 2008, and it was moved by rail to Bo'ness, where it arrived on 14 November 2008. The locomotive is now restored back to working order by the SRPS diesel group and renamed Isle of Mull.
