Bear in mind, too, that the Wilson government of 1964-70 - the one elected on the promise of stopping many of the Beeching Report closures that were planned, but instead accelerated the process - was wedded to having the UK at the forefront of "The White Heat of Technology", and steam was regarded as going against that, despite the BR Standards having been built with a view to running until the 1990s and replacement by electrics. OK, the 1955 Modernisation Plan had put a big hit on the older steam traction, but there was supposedly scope for both steam and diesel traction until electrification could replace both. Then, of course, you subsequently had what was effectively a p***ing contest between certain Regions as to who could eliminate steam quickest, but, certainly in the case of the Western, the Big Freeze of 1963 showed that up to be a bit premature...
