What is a bullet train? What's the difference between a bullet train and an ordinary train?

1, EMU, the full name of power vehicle, refers to vehicles equipped with power devices in the rail transit system, including locomotives and power cars. Motor vehicles are equipped with driving wheels, and the corresponding vehicles without driving devices are trailers. If the train can run normally on the track, it must have a moving car to provide enough traction for the whole train, but there is no need to hang a trailer without power.

2. EMU is a railway vehicle equipped with wheel-driven mechanical equipment, not an EMU. Not only high-speed trains have bullet trains, but all types of vehicles have bullet trains, including constant-speed EMUs, ordinary-speed trains, subway trains, light rail trains, monorails and maglev trains.

3. Bullet train and locomotive are not exactly the same. Locomotive refers to a rail vehicle which is set at both ends of the train and has the function of controlling the train operation. Traditional locomotive is the main body of locomotive. They not only have traction devices, but also have a series of control devices, which use the cab to adjust the main normal work of the whole train. With the appearance of new trains, some trains no longer put the driving wheels in the locomotives, but all of them are installed in the intermediate carriages, such as China Fuxing train.
