China high speed trains, also known as bullet or fast trains, usually reach 300 km/h, or a top speed of 350 km/h.

HSR trains, track and service are owned and operated by the China Railway Corporation. The system developed rapidly in China over the past 15 years thanks to generous funding from the Chinese government. 

Chinese builders use elevated lines to keep high-speed rail tracks straight and level over uneven terrain, and to save on land acquisition costs. Much of China consists of mountains and valleys which necessitates a tremendous number of bridges and tunnels. Unlike the "conventional" (non-CRH trains), which run round the clock, most high-speed rail lines shut down each night.

About 2,600 pairs of high speed trains run daily connecting over 200 cities in China and covering 32 of the country's 34 provinces. As of 2017, China had the world's largest high speed rail (HSR) network with a length totaling over 22,000 km. The Beijing-Shanghai high speed train links the two megacities 1,318 km away in just 4.5 hours. The world's longest HSR line, Beijing-Guangzhou, extends 2,298 km  and is expected to run to Hong Kong by 2018.

Bullet trains are fast, punctual, comfortable, convenient, and economical -- and are the first choice of most travelers -- especially for long distances.

Business class on high speed trains is the equivalent of the first class in airlines. All the attendants of CRH trains are selected on the standard of flight attendants and can speak some English.

A water heater is available at the end of each coach where passengers can get boiled drinkable water.

Most high speed trains use the western-style toilets and all coaches are smoke free.

There are power sockets at the bottom part of each seat back and a luggage rack overhead. There are also luggage closets at the connection area of the coaches coaches.
