The CR200J Fuxing (Chinese: 复兴号; pinyin: Fùxīng Hào) is a Chinese trainset consisting of a power car paired with unpowered passenger cars operated by China Railway. It is the slowest member of the Fuxing series, and only member of Fuxing series designed for existing railways under 200km/h rather than newer high-speed railways.[3] The train was jointly designed and produced by six companies under CRRC.

These units are nicknamed Green EMU[4] or Hulk by the Chinese media,[5] or "trash can", "A&D calcium milk" (for 3rd generation CR200J-C units produced from 2023 onwards) among the railfan community due to its green appearance (for the former type) or resemblance to the Wahaha drink of the same name.[6]

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.[7] 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.[8] On 5 January 2019, China Railway announced several new service lines, and the CR200J was formally put into service.[9]

CR200J shares similar transmission and motor system with other Fuxing series trainsets, despite the lower operating speed.[10][11] All CR200J trainsets are painted in a green livery, reminiscent of China's previous generation green-skinned train.[12] 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.[13]

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.[14] A combination of diffusion and distributed oxygen systems are installed to help alleviate altitude sickness for passengers on the trip.[15]

Equipment issues

In its initial operation period, the CR200J variant manufactured by CRRC Dalian had a high rate of failure. A malfunction in the engine system caused the train to slow down and stop. Out of the 23 EMUs produced by CRRC Dalian, 12 of them have broken down before 1 June 2019. According to a China Business Journal, the maintenance department of the manufacturer was held accountable for the failures. In response, CRRC Dalian cut salaries by 20 percent and recalled their trainset for repairs and upgrades.[18]
