Its one thing that a transport corridor is out of use, quite another that its effectively gone for good.
It is only by sheer good luck that the GW formation through Snow Hill survived to be used again. Without it, transport within the Birmingham area would very different.
The real sham of the 'Beeching' closures was the way that they were presented. Branch lines were treated as if they were completely divorced from the rest of the system and contributary revenue to other services was ignored. In point of fact, many branch lines
were effectively isolated by the deliberate manipulation timetables to give no useful connections. Another aspect was the 'historic' nature of some of the services where the branch train had always been
just that instead of being a through service to the nearest important centre.
To take the example of my own patch, the South Wales Valleys, services which did not run through to Cardiff were axed. Why, in the ninteen sixties, would anyone want to travel from Aberdare to Abercynon? The vast majority of passengers would want to go to Pontypridd or Cardiff and the ten minute wait for a connecting service (each way) added a severe time penalty to what was, and is, a relatively short journey. The neighbouring line to Merthyr Tydfil survived, with a much less concentrated population and less potential, simply because it ran through to Cardiff.
When Aberdare reopened for passengers, it was a point of policy that
every train ran through to Cardiff. Is it feasible that that the people of the Cynon Valley today are fundamentally different to their parents and grandparents? In the years between closure and reopening, there have been road improvements and a vast increase in the proportion of car ownership in the area, so
why do people use the train? The answers are self evident. The people are no different and all that they needed was a train service that was a
service and not an imposition. Since reopening the Aberdare line has thrived.
The foregoing paragraph can be repeated in relation to the Vale of Glamorgan; Maesteg and Ebbw Vale, all of which are to be electrified. Don't forget that these were lines that Beeching etc. convinced a gullible public were of no further use to the community.
Everyone in railway management, in the sixties, was aware of the changes taking place as traditional heavy industry was disappearing from the valleys. The valley lines would be needed as never before, not for coal but as commuter routes to take people to and from the jobs which were becoming concentrated on the rapidly growing coastal belt. The problem was that that kind of thinking did not suit the orthodoxy of the Gospel According to Beeching and some irrepairable damage was done in his name.
