The Inter-City 125 was the brand name of British Rail's High Speed Train
(HST) fleet, which was built from 1975 to 1982 and was introduced into
service in 1976. The Inter-City 125 train is made up of two Class 43
power cars, one at each end of a set of carriages (the number of
carriages varies by operator). The train operates at speeds of up to 125
mph in regular service, making it the fastest diesel-powered train in
the world, a record it has held from its introduction to the present
day. After four decades, most of the HST fleet is still in front-line
service, with various UK train operators. This fascinating Inter-City
125 High Speed Train Owners' Workshop Manual looks at the evolution and
anatomy of the Inter-City 125, along with details of the operation and
servicing of the trains, views from drivers, and details of how the
trains were modernised for the 21st century.
