BR and Beeching get a lot of criticism when all they were doing was implementing government policy. It was government who refused to remove common carrier status, it was government who decided the railways must pay their way. They brought in Dr Beeching to do it.
Don't forget that Beeching was brought in by Transport Minister Ernest Marples, who happened to have been one of the founders of Marples Ridgway, civil engineers, and (amongst other things), builder of roads & motorways.

Some railways were built mainly for freight, with passenger services as an incidental benefit. When freight declined, the passenger services were inevitably at risk of closure. Other lines can only be described as "basket cases", built either in periods of railway mania, or arising from inter-company competition tactics to stop your rival company entering "your" territory. However, I think that some passenger services suffered because of incompetent management. I suspect that the main potential users of passenger services (pre-Beeching era) would be "workers", followed by "shoppers" and the "leisure trips". However, if you look at some old timetables, you see that the services provided would have been pretty useless for most potential passengers.
In the 1950's, apart from shift workers, many people started their workday between about 08:00 and 08:30, with a minority starting at 09:00 or later. Finishing times were often between 17:00 and 17:30, and flexi-time was rare or non-existent.
A couple of examples:-
1. Witham - Wells - Yatton. Nearest large towns or cities : Bristol or Bath. Bristol Temple Meads is some distance from the city centre, so you probably need to arrive there 15 to 20 minutes before you start work. First train from Wells (1953) got you into Bristol T.M at 08:18; first train through from Witham got to Bristol at 10:13. So, you lose most of your potential passengers by providing a hopeless service.
2. Ashbourne - Uttoxeter. The latter is fairly small, so more potential for passengers changing at Uttoxeter for connections to Derby or Stoke on Trent. (1947 timetable) First train from Ashbourne arrived Uttoxeter 07:47 - with onward arrivals in Derby at 08:48, or Stoke at 08:58. Last return of day from Uttoxeter was 18:17, with connections from Derby at 17:08 and Stoke at 16:43. You could also go north from Ashbourne to Buxton (first arrival 08:53), with connection to Manchester arriving at 09:49). The last return from Buxton was at 17:55, with a risky 4 minute connection (SX) from Manchester at 16:40 (16:00 on Saturdays). And some manager probably wondered why they got so few passengers.
Next - the long ASLEF strike in 1955 caused mortal damage to many rail passenger & freight services. Those on strike probably thought they were indispensible to the economy. Passengers and freight users decided otherwise. Whilst road vehicle use was already increasing, the 1955 strike was probably a major factor in encourage people to move from rail to road transport in the years following 1955.
Hence, some Marples-Beeching era closures must have been inevitable, but others should have been avoidable.
