I always get confused by people saying public transportation makes no sense for rural people. I think it makes more sense, provided you use the right kind of public transportation for the right kind of rural community.
A large, spread-out community? Perhaps not so much.
But a small town where 80% of the people commute to surrounding cities? That'd be a great case for 1 or more commuter train, depending on direction and demand.
That is the UK basicially. You need some connecting dots probably to make it worthwhile.
But even then if the train is hourly you need to be organized. No going out ona whim.
