That's called trains.

• bogle 7y ago
  And isn't it interesting that even though we've had driverless trains for decades many of them still require a driver? In London the DLR (Docklands Light Railway) is fully automatic. In Tokyo the trains are computer controlled but a driver takes over outside of peak hours, apparently for practice. So perhaps we'll never get past a self-driving car requiring a human operator at least pretending to pay attention (so no real change there, then).
