The Class 40 of British Rail (ways) were general-purpose locomotives with diesel-electric drive in use from 1958 . The last of the 200 machines built up to 1962 was retired from active service at the beginning of 1985. Seven locomotives have been preserved.
They were initially called Type 4 after the manufacturer's name, English Electric , and were listed as Class 40 from 1973 with the introduction of TOPS vehicle management.
The best- known locomotive of the series was No. D326 involved in the mail robbery on August 8, 1963. The machine, later designated 40 126, was scrapped at the Doncaster Railway Works in 1984 .
History and technology
The mechanical and electrical construction of the Class 40 / Type 4 series was based closely on that of the Southern Railway diesel locomotive 10203. The bogies , the motor unit and the drive accessories were largely identical. The unusual bogie did not have a pivot. The locomotive body rested on lubricated segment bearings on the side.
The main difference was in the design of the locomotive body. The side surfaces of the locomotive body ran in a straight line, the driver's cabs were located behind pronounced front noses, which contained the auxiliary equipment.
The class 40 performed well in passenger and heavy freight train service. The heavy weight of the locomotive limited its use on express train lines. Initially based in the Eastern, North Eastern and London Midland regions of the BR, they pulled such well-known express trains as the Flying Scotsman , the Royal Scot , The Master Cutler , The Norfolkman and the Queen of Scots pullman suit . In its later years, the 40 series migrated to inferior areas on subordinate routes.
Whereabouts
After being damaged in an accident, the D322 was the first locomotive to be parked in September 1967 and dismantled in Crewe in November 1967 .
The actual shutdowns began in January 1976. The arrival of the BR high-speed trains eventually led to their replacement and all machines were shut down until early 1985.
Others
The locomotives were painted in what is known as "Brunswick Green", with yellow rectangles on the front. The roof was painted silver gray. The bogies were painted gray-brown, the buffer beams were red.
The Class 37 , of which 308 machines were built, was created as the “little sister” of the Class 40 .
