To move up to East Anglia, the Lowestoft to Yarmouth line was closed post-Beeching; I remember it running in the late 1960s. A problem with it was that it didn't connect at Yarmouth with the line from Norwich; it went to South Town, which had declined sadly after the direct line from Beccles was closed. The three terminal stations at Yarmouth were quite separate with only a very indirect connection between two of them, South Town and Beach, and the latter had closed by the 1960s.
If I may return to this thread
A few mentions of the Woodhead line, although that was covered by the Hope Valley line...Waverley Line local traffic to Hawick but duplicated as a through route by the WCML.
No single route has had peeps on here up in arms over its closure. None of us want to see lines closed obviously.
Bottom line is there really hasn't been a major irreplaceable main route closed, by Dicky Beeching or anyone else.
Quite a lot of us "peeps" didn't have the opportunity to be up in arms over the many irreplaceable routes closed.
Daventry is probably the biggest town with no railway station so I will go for the Leamington to Daventry line.
The one closure that should have never happened and wasn't part of Beeching was that of Blackpool Central. It was the local council that wanted the land to 'redevelop' the land into what turned out to be a huge car park. 4-6 platforms on the excurision side would have closed Blackpool North - Poulton and given up the main Central station by the front for Council use. The Blackpool South line runs through the greater population centres and not closing Central but North could have possibly saved the Fleetwood line (closed 1970) as that would have been the only service left for Poulton, therefore enhancing the economic viability of that line. Hourly Fleetwood - Colne trains anyone?
With the rapid development of Essex in the '70s and '80s with commuter villages, had they survived a few more years, they would have become key parts of commuter systems. Take the Essex lines like: Great Chesterford to Six Mile Bottom.
I think that had the Buntingford branch lasted a few more years, it could well have become a commuter route.
Further to that, if they hadn't terminated the line at Buntingford during construction in the 1860's and had continued as originally planned to connect to the Great Northern at Royston, i feel that line would be here today, electrified and providing a useful diversionary route.
