On another thought, a slower dieselisation process,as well as saving money, should keep steam going longer. Several of the BR Standard classes - the Britannia class, 9Fs and a host of smaller designs -could have gone into the 70s. In OTL, some of these designs were built several years after my Dad was born in 1952, and they were all gone a few months after he'd done his O Levels in 1968.
Compare this to the "Pacer" class 142. Designed by moulding a 16 ton wagon chassis and a Leyland National bus body, these horrendous pieces of low cost kit were built as a stop-gap, first rolling off the production lines in 1985. They must be withdrawn in 2019, as they cannot comply with disability legislation.
An even more extreme example. My father vaguely remembers the LNER G5 Class (originally NER Class O), one of which is currently being built from scratch. These locos ran most of the North Eastern's passenger branch line services from their introduction in 1894-1901. All of them survived to see BR, being withdrawn between 1950 and 1958!

Forgiven, my good man. That particular TL has been on an ever growing list of ones I want to get around to reading. After seeing that particular post, it has gone to the top.Also, forgive the blatant plug, but if you fancy looking at my own foray into rail-alt-hist, plenty of it can be found in this chapter of my 'Red Britain' TL, which is written in-universe by a notable OTL figure.
