Nick Howes has sent me a link to the map which accompanied the notorious Beeching Report. Most of the lines shown here to be closed - including our own S&D - were indeed closed, but a few did survive, including many of the Cornish brances, the Exmouth branch, the East Suffolk line, the Cumbrian Coast line and the Central Wales line. I'd argue that the S&D was and is far more important than any of these routes and should not have closed even if it had found its way on to the Beeching Report. (Neither of course should any of the others listed ...)
On a lighter note Compulsory Purchase Boy has returned, I suspect he has an inset day at school! He now reckons that the 'people than run the world' will continue to drill for oil (which is now so expensive to find that it would be hard to find a market for it) and will also deliberately build on railway trackbeds to block lines reopening! Ah, the addled and conspiracy-theory-riddled minds of 14 year old boys - reality will come as such a shock to him in the coming decades!
With the school holidays now almost upon us I suspect we'll be getting a few more gems from the lad himself over the coming weeks!
