There are houses built on the trackbed on the Plymouth side of Tavistock. I believe though, that the trackbed to Okehampton is still pretty much intact.
When I saw the headline, I was hoping that it might be the old GWR line via Yelverton and Horrabridge.
Tavvy South station might be a bit of a problem though…and also the Grenofen viaduct - is that wide enough for trains or is it just a walk/cycle way?
There are indeed about 25 houses on the old track-bed between the end of the large viaduct which overlooks the town and Tavistock North Station. At the Okehampton end of the Station site, the West Devon Council offices are on the edge of the old track-bed.
They have been talking about re-opening the Bere Alston to Tavistock line for at least 30 years. I've been to a few presentations over the years.
Inintially, it was hoped to get much of the funding from the EU and then laterly, from the new residential development that has been built on a green-field site next to the A390 on the road towards Gulworthy.
The intention was to also build a new Station on this site, which is well away from the town and would thus require rail passengers to use their cars to get out there, somewhat defeating the aim of the exercise.
I believe that to make it viable and practical, the line would need to come into Tavistock North again, in the middle of the town.
Sadly, its never going to happen, as will be the case with a number of the other transport projects announced by Sunak to great fanfare at the Conservative Party Conference when he cancelled HS2, only to back-track on these "pledges" within days via the internet.
