  • Patent number: 10328960
    Abstract: A train system has a locomotive traveling at a controlled speed on a main track, with passenger cars capable of locomotion and of automatic coupling and decoupling, forming a train on the main track. Appropriate passenger cars are decoupled and switched onto a side track at stations to unload passengers while the rest of the train passes the stations without stopping. Passenger cars loaded with passengers at these stations are then deployed to couple-up with the train after it has passed the station. This combines local service with express service. Operation in most cases is guided by a central computer system.
