Br Diesel Locomotives In Preservation

When British Railways (BR) initiated its Modernization Plan in 1954 it had little experience of diesel locomotives thus initiated a Pilot Scheme to trial combinations of the three elements comprised within a locomotive the engine, transmission and body.The initial orders for 174 locomotives were placed in November 1955, but even before the first locomotive had been delivered, changes in Government policy led to bulk orders for most designs being trailed. It was only in 1968, once steam traction had been removed from the network, that BR was able to review the success, or otherwise, of its diesel fleet and decide which designs to withdraw from service.The nascent preservation movement of the time was concerned to preserve steam locomotives whilst only buying diesel shunting locomotives for support roles on heritage lines and it wasnt until 1977 that any effort was made to preserve main line diesels. Once it was confirmed that diesel locomotives had an appeal to enthusiasts, further purchases were made that resulted in examples of most of the BR diesel classes being represented within the preservation movement.Fred Kerrs book details those classes which are represented on heritage lines, identifies where possible their location as of December 2016, shows many of them at work and shows what is involved in the restoration, maintenance and operation of diesel locomotives by the volunteers whose efforts are vital but rarely acknowledged.Some of the preserved locomotives were bought for possible use on the national network and this was facilitated by the Railways Bill 1993. A complementary album of preserved and heritage locomotives titled Heritage Traction on the Main Line details the locomotive classes whose representatives are still in regular use on the national network as at December 2016 and follows a similar format to this album.

When British Railways initiated its Modernization Plan in 1955, its Western Region elected to trial locomotive designs with hydraulic transmission whilst BR encouraged designs with electric transmission. The Western Region felt that the lighter weight of 78 tons for a diesel hydraulic locomotive producing 2000 hp, compared to an equivalent weight of 132 tons for a diesel electric locomotive producing 2000 hp, would better meet BR's requirement for a modern locomotive. BR's failure to follow up with its declared policy of having all freight vehicles fitted with brakes saw operators preferring the heavier diesel electric designs which proved more able to operate trains without through brakes at higher speed. The greatest concern was with operating costs whereby the Western Region policy of replacing components at the depot then transferring them to Swindon for repair incurred heavy costs that were reflected in the maintenance cost per locomotive. Given the smaller number of diesel hydraulic locomotives and the larger number of diesel electric locomotives it was little surprise that by the mid-1960s a cost comparison showed that the build and operation of diesel electric locomotives was increasingly cheaper over the long term. Furthermore the increased availability of diesel electric locomotives released by a combination of factors provided an opportunity to replace the diesel hydraulic fleet, which was withdrawn from service during the 1970s. The preservation of redundant locomotives was slow but once it was confirmed, by the preservation of 'Hymek' Class 35 D7017 in 1975, that public appeals could quickly fund the preservation of withdrawn examples further public appeals followed. In a short space of time 31 locomotives from a mixed fleet of 358 locomotives entered preservation to remind both enthusiasts and the public of a concept (i.e. hydraulic transmission) that had had much to offer but had been dismissed on questionable financial grounds.

In an earlier album titled BR Diesel Locomotives in Preservation Fred Kerr detailed the many classes of BR diesel locomotives that had been preserved and noted that some purchases had been made with the hope of operating them on the national network.The Railways Bill 1993 provided an opportunity for this to happen and this album shows such locomotives at work during the early part of the 21st century up to December 2016. During this period many new train operators entered the market and their early operations used elderly locomotives withdrawn from service by their original operators until their business(es) were established and new locomotives could be bought. On occasion these new companies were prepared to hire preserved locomotives with main line access to service short-term contracts and these, mainly freight, services provided much of the variety of locomotive operations that offset the increasing sight of multiple unit train services that epitomize the modern railway.The author has chosen to consider heritage traction as any locomotive older than twenty years, which therefore includes electric locomotives but excludes those of that age which are still operated by their owners as at April 1 1994 when British Railways (BR) was privatized. This results in the Class 59 fleet being excluded because its ownership has been constant but the Class 60 fleet being included because of purchases by Colas Railfreight after that date.

A stunning pictorial survey of the Class 37/4s, covering their operations in Scotland, England, and Wales. In the prelude to the privatisation of British Railways, the Provincial Sector (later Regional Railways) became responsible for local / secondary train services. It initiated the refurbishment of thirty-one Class 37 locomotives, fitted with train heating equipment—hence designated Class 37/4—to support the shortfall of DMU trainsets. Their initial task was to work services on Scottish lines radiating from Inverness to points north and Glasgow to service the West Highland Line with a small batch based in South Wales to service Cambrian Line services and services from Cardiff traversing the Marches Line to serve Liverpool. These services were soon replaced by Sprinter trainsets thus releasing the fleet to other duties including freight operators hence, at privatisation in April 1994, the fleet became owned by freight companies who subsequently hired locomotives to both other freight companies and passenger operators. Throughout their working life, the fleet members have proved invaluable and capable of powering a variety of services whose history confirms both the locomotives’ adaptability and prowess in handling the duties allocated to them. Fred Kerr’s book seeks to show this adaptability by detailing the reason for their initial creation and the tasks successfully undertaken once released from their initial roles as support for the shortage of DMU trainsets. The advent of privatisation saw an increased demand for their ‘go-anywhere do anything’ ability which is also displayed by the range of photographs that illustrate the wide range of duties performed by class members. Once withdrawn from service some class members were purchased for preservation and—such was their adaptability—that preserved examples were hired by train operators to cover duties that no other class of diesel locomotive was capable of achieving.
