关于此电子书

The Southern Region of British Railways had long sought to design a locomotive capable of working on electrified lines and non-electrified station yards and sidings. In 1959 British Railways approved a design, designated Class HA, later British Railways Class 73, which combined the electrical equipment of the latest EMU design with the standard English Electric diesel engine in one bodyshell. An initial order was placed for six locomotives but allocated to Eastleigh Carriage and Wagon Works because the design used stock components normally found on the multiple unit fleet.

The locomotives were released to traffic during February 1962 and were allocated to Stewarts Lane depot from where they powered the mundane duties of freight, parcels and empty stock services. They also tested the principle of high-speed propulsion of passenger trains prior to the adoption of the principle for the electrification of the Waterloo – Weymouth line as far as Poole. Included in this scheme was the ordering of a further 43 improved Class 73 locomotives which were built by English Electric.

The locomotives proved a useful design but when British Railways was privatised in 1994 the new operator considered them surplus and sold them out of service. The original 6 locomotives had already been transferred north to Merseyside to work on the local electric network. Although initially considered unsuitable by the original operator they were highly regarded by many companies hence were sold on to continue working on the national network. Some were converted for special purposes thus were formed into sub-classes hence as at December 2022 30 of the 49 fleet still remain active in mainline service.

作者简介

Fred Kerr was born in Edinburgh in 1948 where he gained an interest in railway locomotives from both the LMSR and LNER companies whose services permeated the local network. When his parents moved to Corby in 1956 the local steelworks provided further interest from its mix of freight services, including seeing the last of the Beyer Garrets and the replacement Standard Class 9Fs whilst the industrial locomotives of the internal steelworks network offered further insight into the variety of steam locomotives. This was a time of change and during the 1960s the interest in locomotives included the new order of diesel and electric traction without reducing the interest in steam traction. While his interest in Diesel Traction led to his early involvement with the Diesel & Electric Group and its preservation activities during the 1970s, his move to Southport in 1982 restored his opportunities to return to his first love of viewing steam locomotives at work and this album records some of the locations that he chose to visit and the locomotives that he was able to photograph.Today his interest continues as a life member of the A4 Locomotive Society, Keighley & Worth Valley Railway and Ribble Steam Railway whilst he also support bodies concerned with preserving steam locomotives, diesel locomotives and infrastructure extensions.
