The concept of multiple unit has entered the horizon of the Chinese since the 6th Speed-up Campaign of [[China Railway]] in 2007. With the upgrade of [[Jinghu Railway]], North [[Jingguang Railway]], [[Jingha Railway]] and [[Hukun Railway]], and the construction of new Passenger Dedicated Lines (or Passenger Railways) completed, [[China Railway High-speed|CRH]] (China Railway High-speed) trains have been put into service, mainly in North and Northeast China, and East China. All these CRH trains are electric multiple units. This was the beginning of the general service of multiple unit trains in China's national railway system.

Far earlier than the introduction of CRH brand, multiple unit trains have been running on all major cities' metro lines in China.
