The Western Region had some diesel electrics fairly early
on, including Classes 37 and 47, the hydraulics only having a monopoly in
the South West. But gradually the non standard hydraulics were
replaced by diesel electrics from other regions from the end of the 60's,
the hydraulics were all replaced by 1977. The classes brought in were
Class 31's from the Eastern Region, class 25's from the London Midland,
Class 46's from the Eastern and the redistribution of locos and their duties
involving Classes 37, 45, 46 and 47 followed by the move of the whole of
Class 50 from the Crewe - Glasgow route following its electrification, and
finally the Inter City 125's arrived to complete the process.
To start with, three photos of a selection of
locos both hydraulics and electrics at Bath Road (left) and Cardiff Canton
(centre and right).

diesel electrics on the Western Region, click on a photo for that classes

One other type of diesel electric that was new to the Western
Region was the "Blue Pullman" sets, one of which is seen here arriving at
Cardiff in their later silver grey and blue livery.
