The development of CR200J was initiated by
China Railway Corporation to create more affordable, economical, and efficient high-speed rail. Development started on 28 August 2015, and by 27 April 2017, initial prototypes had entered testing. Multiple trainsets were sent to the
China Railway Chengdu Group for dynamic testing on the
Chengdu–Chongqing railway,
Chongqing–Lanzhou railway, and
Chongqing–Guiyang high-speed railway between 17 December 2017 and 4 January 2018. There are multiple variants of the CR200J series made by different subsidiaries of the state-owned China Railway, and these variants are required to follow the China Standardized EMU design philosophy, thus ensuring that every variant of CR200J is compatible to each other. Another round of testing was finished on 5 August 2018. On 5 January 2019,
China Railway announced several new service lines, and the CR200J was formally put into service. CR200J shares similar transmission and motor system with other Fuxing series trainsets, despite the lower operating speed. All CR200J trainsets are painted in a green livery, reminiscent of China's previous generation
green-skinned train. The interior design follows the design language of CR400 Fuxing EMU trains, and are fitted with individual power outlets, Wi-Fi connectivity, and larger legroom. On the
Sichuan–Tibet railway, the plateau variant of the China Railway CR200J, the CR200JS-G
electro-diesel multiple unit specifically designed for plateau operations with weather resistance it used. A combination of diffusion and distributed oxygen systems are installed to help alleviate
altitude sickness for passengers on the trip. ==Variants==
