There's an idea to re-open from Plymouth to Tavistock and maybe one day onto Okehampton which would provide an alternative if it kicks off again at that there Dawlish with all the climate change malarkey.
Closing the "Withered Arm" was also largely an act of spite when the routes were transferred to BR Western Region.
A bit more complicated than that - yes -a rift between what were termed green badge (Southern staff) , and brown badge staff (Western Region) ,but the truth is that Beeching and before planned massive cuts to the West Country (and the rest of the country) as matters changed. The late and great Gerry Fiennes, one the very best railwaymen ever as General Manager at Paddington ( ex LNER so no baggage about the West Country) , worked incredibly hard to repurpose the railway down there and way was / could have been "nothing west of Plymouth" , saw the Penzance end saved and great efforts to modernise what freight that was - largely china clay to Fowey ,but he developed long distance clay to Stoke on Trent / Sittingbourne and elsewhere (nicked from coastal shipping) ,even a Freigthtliner service and much more. Local services were "modernised" with diesels and cost cutting done. (frankly - some of the far west lines were built in the mind 1920-s and never, ever , made any money and never would) - so by working away with what we could not call stakeholders and staff, much more was saved.
Salisbury to Exeter was for the chop ,but he largely got that saved - albeit with a 2 hourly service and diesels , and was built back later, as this view of "one line only , and only some of way to the West" - was rescinded.
Remember , much was seasonal traffic and the ever present car took so much away from the 1950's - it was very hard , especially for the very proud Southern railway cadre who saw much of their life work changed in the 1960's and beyond (for example the loss of Exeter Central as a Divisional Office and all that went with that , but I do not think it was really malicious desperate times needed pragmatic action.
I have nothing but respect from those in BR who worked in the area , or were brought up in the area , but there were very positive comments on the pride and quality of the Green Badge staff - of all grades.
That comes from a hopeless advocate of Wales and the best bits of the Great Western ! (If only Fiennes had spent more of his valuable time within South Wales - most of that had to go in the harsh times - but a few valuable bits could have been when saved - but he saved (amongst many , many things) - or developed the national Inter City concept etc.......talking to people who in their youth met him , they were all in awe of his seniority , but relaxed with his sound humitarianism , practical and commercial sense etc etc ....he always said a railway manager needed "a sense of time , a sense of money and a sense of humour"- I have used many of his quotes in many lectures and meetings over the years.
Thank you for your patience ........(PS - always had / have a very sort spot for the Southern - particularly the Southern Electric !)
