Diesel Locomotives

BRBritish Rail or British Railways Class 37 37308 is the last British Rail Class 37 diesel locomotive to be built, dating to 1965. It is owned by a group of SVRSevern Valley Railway diesel members, several of whom also part-owned former resident 37906 and are shareholders in the Class 50 Alliance.

37308 in service

In 1959, British Railways placed an order with English Electric for a batch of 42 1,750HP Co-Co diesel-electric locomotives similar to two designs EEEnglish Electric were constructing for narrow gauge lines in Africa: the Sudan Government Railways 1000 Class (3ft 6in gauge)[1] and the East African Railway 90 Class (metre gauge).[2] All three classes used EEEnglish Electric's 12CSVT diesel engine, and the British Railways examples were very successful. Six further orders resulted in a total of 309 locos entering service with British Railways between 1960 and 1965.[3]

37308 was built at EEEnglish Electric's Vulcan Foundry in Newton-le-Willows, works number EE/VF3568/D997, and entered service in December 1965 numbered D6608.[4] The loco spent most of its early working life in South Wales, first allocated to Landore Depot in Swansea with spells at Cardiff Canton and Bristol Bath Road. It was renumbered to 37308 in March 1974.

It had its last classified repair in Doncaster in 1988 but, unlike many other class members, it was not rebuilt into one of the new sub-classes. At sectorisation in 1989 it was allocated to Freight Coal sector and renumbered again to 37274, with subsequent reallocations to the Metals sector and moves to Scotland, Toton and Eastleigh.

It was stored in 2000 and reverted to its 37308 identity, becoming part of the EWSEnglish, Welsh & Scottish Railway, a rail freight company heritage fleet. During this time it visited a number of heritage railways while remaining in capital service. One such visit was to the SVRSevern Valley Railway and the April 2001 diesel gala. It returned to mainline use from 2002 and was allocated to Sandite trains in 2004. It was withdrawn in 2007.

37308 in preservation

It was purchased for preservation on 18 November 2007 and allocated to Kidderminster - Private Owner Diesel Locomotives just three days later. The SVRSevern Valley Railway Board agreed at the time to accept it onto the Railway after restoration.[5] Between 2007 and 2012 it moved between Old Oak Common, Eastleigh, Cardiff Canton, RVEL at Derby and Lydney on the DeanWilliam Dean, Chief Locomotive Engineer of the Great Western Railway 1877-1902 Forest Railway undergoing overhaul. This included being heavily stripped down in order to try and overcome the years of rust and rot which had taken its toll on the loco. A report of progress in 2010 noted that "...the locomotive appeared to be in fairly good order when bought for preservation, but deeper investigations revealed that the foam that had been pumped into many of the voids in the floor space and other areas to improve the cab environment by blocking draughts, etc, had broken down and had absorbed large amounts of water. Consequently, many of the electrical conduits and brake pipes that are also in the floor voids have rusted through and need to be replaced".[6]

In January 2018 and June 2019 the Chairman of the SVRSevern Valley Railway Diesel Committee referred to 37308 being under restoration for use on the SVRSevern Valley Railway.[7] It arrived on 12 July 2020 for restoration to continue at Kidderminster TMD. It arrived with bogies with new size tyres and the engine, generators and radiator compartment overhauled. An electrical contractor had previously been engaged to rewire the loco. Based at the SVRSevern Valley Railway, it will have its overhaul completed at Kidderminster, hopefully to start in 2023[8][9].
