For Hans - I know you're writing at a distance so it's hard to be accurate. The trail has various sections but right now only Portsmouth to Hampton New Hampshire are open for 8 miles (not that long). Eventually this is planned to go as far as Newburyport Massachusetts by linking to other trails. Repair stations are completely normal on rail trails here but I have yet to actually see someone make use of them.

I did about half this rail trail from Breakfast hill road to the end in Hampton. All stone dust. Through nice areas but unusual for other trails it often doesn't link to roads it passes by. Will be a great asset when completed. https://nhseacoastgreenway.org/

a very long and really beautiful, well-maintained bike path. It used to be an old railway line. Now there are even repair stations along the route - completely unusual for the USA. The path is very long and starts in Greater Boston and goes right up to the city. Super
