The CR220J Fuxing (Chinese: 复兴号; pinyin: Fùxīng Hào) is a prototype Chinese electric multiple unit developed and manufactured by multiple CRRC subsidaries. As part of the China Standardized EMU family, the CR220J has an operating speed of 200 km/h (120 mph).
Development
[edit]2023
[edit]The CR220J finished design phase and entered manufacturing process in middle 2023.[1][2]
2024
[edit]In March, the first power car entered testing process.[1][2]
On April 20, first FXD1D-J rolled out at CRRC ZELC factory in Zhuzhou, Hunan and travelled to Nanjing, Jiangsu for further testing with the trailers.[1]
On April 29, first FXD3D-J (FXD3D-J0001) rolled out at CRRC Dalian factory in Dalian, Liaoning and travelled to Tangshan, Hebei for further testing with the trailers.[2]
On May 18, first whole set of CR220J1 (CR220J1-2601), combined with one FXD1D power car and 8 20AB trailers travelled from Nanjing to China Academy of Railway Sciences (CARS) testing site in Beijing.[1] At the mean time, the first whole set of CR220J3 (CR220J3-1601) also arrived at the CARS test center in Beijing from Tangshan.[2]
On August 4, the CR220J1 and CR220J3 leaved CARS test center in Beijing and headed to Chengdu, Sichuan for testing on conventional lines.[1][2]
On August 8 and 9, they arrived in Chengdu and started testing on Chengdu-Chongqing railway (Chengdu-Zizhong section) and Chengdu-Kunming railway (Shuangliu-Ganluo south section).[1][2]
Design
[edit]The CR220J is a further development of the successful CR200J platform. Unlike other electric multiple units in the China railway fleet, the CR220J uses similar technology like the German ICE 1, ICE 2 and French TGV, which concentrates traction units into single or double power heads in combination with unpowered carriages as a train set instead of separating the power source all across the set.
Power car
[edit]The power car of CR220J is designated as FXD1D-J and FXD3D-J, which are developed on the “Fuxing” electric locomotive platform. Each power car has a traction power of 7200kW, which is 28.5% more than the previous generation FXD1 platform that can be seen on CR200J. FXD1D and FXD3D are believed to be packed with structures and technologies from six-axle HXD1D and HXD3D electric locomotives with localized components that are manufactured in China.
Trailer car
[edit]The trailer cars are designated as 20AA and 20AB, 20AA is manufactured by CRRC Tangshan[2] and 20AB by CRRC Nanjing Puzhen[1]. They are the further development of the trailers cars on the CR200J, which can be traced back to the imported Bombardier carriages. Redesigned SW-220G bogies are deployed on these carriages for more stability under higher speeds.
Variant
[edit]CR220J1 Prototype
[edit]The power car is designated as FXD1D, designed and manufactured by CRRC Zhuzhou Locomotive[1] with a power of 7200kW.
Trailers are designated as 20AB, manufactured by CRRC Nanjing Puzhen.[1]
