Inclines, monorail (not the kind your thinking of, see "https://www.youtube.com/watch?v=Ei6LKHNFpeE"), and cable car are all solutions to this first problem, it doesn't just have to be trains, that was an example. Yes the disabled exist, yes motored wheelchairs exist. That one was easy. And finally you bring up services, yes, services need vehicles, but I, personally, believe that sticking them on tram lines is best to make them completely predictable, except ambulances, which I do not know.
@xVAF @mitgibs @stux For an ambulance you might use a car-type, or a little push cart you load on a tram/bus/rail. Something like that could work, though that I would leave to state medicare officials to know about. (by state I mean nation, not provincial, maybe municipal could work to help in weird situations like Quebec.)
