But 155 mph-ing the route east of Exeter is (a) easier (b) will benefit more people than upping Exeter to Penzance by 10 - 20 mph here and there (c) could get London to Plymouth down to less than 2 hours 30 minutes - hardly remote (about the same as London to Worcester but about twice the distance).
Yes but you dont have competition from Air links to Gatwick and London city airports from Worcester which could well intensify as the 21st century unfolds.Certainly I have seen the Plymouth to Exeter rail route refered to in the local press as "Plymouths victorian rail link to Exeter and the rest of Endland".You can also drive up the A38 dual carraigeway from Plymouth to Exeter(M5) in not much over half the rail journey time.It really is a matter of perception and something needs to be done about it if rail is to be taken seriously west of Exeter in the 21st century.
And you believe what the local rag spouts!!!
The one benefit of rail, as soon as it snows, the airports are instantly shut or you don't run the risk of sitting on Halden/Telegraph hill till the early hours

Whenever I travel on trains heading to Cornwall i'm always impressed at the patronage, far from being devastated by the inconvenient air flights taking you a place 30 mins by train from London.
