at the higher ski resorts you get the chair lifts that seat 6 and have a large “visor” (clearly not the technical term, but only way i can think to describe it) that you can pull down to protect you from shitty weather. however as others have said, the cap ex, running and maintenance on a chair lift would be prohibitively expensive.
about 7 years ago me and some mates got chatting to a guy in a curry house near innerleithan who was doing the feasibility study for the proposed chair lift. he thought it was madness and yet – and i could be wrong here – it got planning permission but no one could afford the £5m it would cost!
it would definitely be cheaper / easier / more realistic to to under take a major road project at BPW
