I'm wondering if it's nothing to do with the propulsion, but simply a way to keep from touching the sides in a narrow tunnel
Wouldnt they have been better off attaching tyres horizontally
Maybe, but if the tunnels aren't consistent in size and they already have the guys there, this might still be the better option
Good point.
I do know this was how they through tunnels when they used mules/horses.
Makes sense that once they had engines this would still be useful.
