What kind of power does the high-speed rail rely on to operate?In China, high - speed rails mainly rely on electricity as their power source.
The electricity for high - speed rails comes from the public power grid. However, before being used by high - speed rails, the electricity needs to be transmitted to the traction substation, where it is converted into single - phase alternating current with a frequency of 50 hertz and a voltage of 25 kilovolts to match the electrical scale of high - speed rails.
In contrast, in the United States, most trains use internal combustion engines. For internal - combustion - engine - driven trains, the diesel engine on the train first converts the chemical energy of the fuel into mechanical kinetic energy, which is equivalent to that of an ordinary generator. Then, this mechanical energy is converted into electrical energy by the generator, and finally drives the electric motor to drive the entire train.
Although both electric - driven high - speed rails and internal - combustion - engine - driven trains ultimately use electricity as the power source for the train to run, they differ significantly in the way they obtain electricity. High - speed rails in China obtain electricity more directly from the power grid, while internal - combustion - engine - driven trains in the United States have a more complex energy conversion process within the vehicle.
