This innovative concept combines the bus and train into one. By switching wheels, it can drive on a highway or on train tracks, thus getting people to destinations faster and easier. Sounds fascinating but I wonder, how long does it take to change the wheels?
Haven’t you seen the railroad maintenance trucks? They are trucks that can drive on streets and also have railcar wheels (smaller than those on an actual railcar) that can be lowered onto the track. The truck drives onto the right of way, lowers the wheels and drives off down the tracks.
I would imagine that this bus/train combo might use something similar.
