Same here, since this is the traditional usage of tram. Google tram and you find the ones running on rails, in wikipedia as well, it is part of rail transport; though Wikipedia says the same Disneyhead said, that in America they are often called trolley.
Would the lane for the trolley be blocked off from other traffic with a small wall or something? I am just wondering, because if it is an open tram and it passes along a public road, could be a liability.
