What is the fuel for high-speed rail operation?
High-speed rail is driven by electricity. The traction motor of electric locomotive or motor train converts electric energy into mechanical energy to drive railway trains, EMUs and urban rail transit EMUs to run. It is mainly composed of power supply, traction substation, catenary (contact rail), track loop, electric locomotive, EMU and other links to realize electric traction.

High-speed railway, referred to as high-speed railway for short, refers to the railway with high infrastructure design speed standards, which can provide trains with safe and high-speed running on the track, and the train running speed is above 200 km/h. High-speed railway has different regulations in different countries, different times and different scientific research and academic fields.

The National Railway Administration of China defines China's high-speed railway as a passenger dedicated railway with a design running speed of more than 250km/h (including reservation) and an initial running speed of more than 200km/h, and has issued the corresponding document "Code for Design of High-speed Railway". The National Development and Reform Commission of China defines China's high-speed railway as a newly-built or existing railway with a speed of 200 km/h or more, and has issued the corresponding Medium-and Long-term Railway Network Planning Document, which unifies all track lines with a speed of 200 km/h into the category of China's high-speed railway network. ?

"High-speed train" is referred to as China high-speed EMU passenger train (G-prefix train) by people and train ticket system under China Railway Corporation (12306 official website), which is actually a mistake.
