What do you get when you combine a train and a bus? You get the DMV (Dual-Mode Vehicle, not Department of Motor Vehicles) from Toyota. Essentially, it's a bus with train wheels that can be lowered to a set of tracks. Or is it a train car with bus tires that can be lowered to the road? In any case, you get the idea.
The DMV is a fuel-efficient people mover that allows a bus to hop on train tracks and get going much faster without danger of crashing. When it needs to go off the tracks, it simply switches wheels, a process that takes about 15 seconds. It's a pretty cool vehicle, one that's already popping up on more rural train lines in Japan.
