Unusually for a large class of locomotives, all Western Class
locomotives had the same prefix which gave them a unique identity.
Redesignated as Class 52 in the early 1970s, they were essentially
designed by and for the Western Region, which saw hydraulic transmission
as the way forward in replacing the 4-6-0 steam locomotives that Swindon
had produced. However, the rest of British Rail went down the road of
electric transmission as the mistakes of the wholesale lunge into
dieselization came to fruition, and when BR opted for a standard policy
the Western Region was forced to comply. It was in 1967 that the death
warrant for the hydraulics was signed, though it would take more than a
decade to finally end the hydraulic era. Illustrated with full-color
photographs of all 74 of the Western Class locomotives, on a variety of
workings that illustrate their versatility, this nostalgic volume gives
a portrait of a much-loved, but short-lived, class of locomotive.
