    A single rail clamp would have a lot of friction because you need contact all the way around the wheel, increasing the surface area. The reason why regular train wheels are so efficient is because they’re balanced on top on a tiny surface area, using the clever tapered shape of the wheels to go around corners without jamming against the side of the wheel.
