Following the abolition of steam on the Western
Region operated lines to the West Country these locos were frequently seen on
services from Waterloo to Exeter and beyond. First introduced in August 1958,
these quite attractive diesel hydraulic locos proved to be a very troublesome
design which could only be used for passenger work as their light weight made
them unsuitable for goods trains. The first three, D800-2, were withdrawn after
just ten years in service with the last loco, D832 Onslaught, being
withdrawn in 1972.
December 1962 saw the lines west of Salisbury
transferred to the Western Region where steam was being phased out much more
rapidly than on the Southern. Soon thereafter the Bulleids were replaced on the
Waterloo-Exeter trains by the 1960-61 Swindon built diesel hyrdaulics of class
42, the Bo-Bo Warships. 2300hp with a maximum speed of 90mph. By the 1970s
greater standardisation was sought for BR as a whole and hydraulic transmissions
were short listed for extinction. By 1974 the warships withdrawn and the service
was worked by class 33 and then class 50 until they were replaced by class 159 DHMUs in 1992/3.
