Yeah but light rail is not good for moving masses of people extremely long distances. It'll shuttle you around town, slowly; but it has the same problem as a bus system: it's very slow. Cars are far superior to buses because cars go directly from where you are to where you want to be, not on a route that eventually gets there; light rail as well, though the only light rail I've seen acts as a shuttle between mid-town and downtown. Very limiting.

This is why I have express rings and train swaps to establish complete routes without change-overs and with few stops. Mass transit has trouble getting you from one place to another, except over long distances: planes are like trains and cars slapped together, freedom of movement (cars) with no traffic and a pretty direct pre-selected route (trains). You don't need to lay track to get a plane to a particular point. Roads approximate this; trains less so.

Yes, I know this will never happen. Also, as for a lot of thought, I shot this from the hip; 20 minutes, tops.
