I've heard from several people that live in Groveton that NHCR was looking at maybe starting a Scenic train and then eventually a passenger train for travel... Again they're probably all rumors but it would be super cool to see a train go through once in a while instead of once every 10-12 months or so...
And would also require an NHCR pilot, let alone a likely inspection of the tracks and approval from NHDOT again.
Then there would be the issue of having nowhere to run the power around between Whitefield and Fabyans without having it awkwardly run at both ends.
