The CR450BF Fuxing (Chinese: 复兴号; pinyin: Fùxīng Hào) is a Chinese electric high-speed train manufactured by CRRC Changchun Railway Vehicles. As part of the China Standardized EMU, the CR450BF is designed to operate at speed of 400 km/h (250 mph) and a maximum test speed of 450km/h.
History
[edit]2020
[edit]Drafted between 26 and 29 October on the fifth plenum of the 19th Central Committee of the CCP, the project was announced as part of China’s 14th five-year plan, known as “Research and development plans for speedier bullet train”.[1]
2023
[edit]On June 28, test runs were conducted on the Fuzhou-Xiamen high-speed railway using two trainsets: CR400AF-J-0002comprehensive inspection train (CIT) containing a CR450AF intermediate car, and CR400BF-J-0001 comprehensive inspection train (CIT) containing a CR450BF intermediate car. During these tests, a speed of 453 km/h (281 mph) was reached, and a relative speed of 891 km/h (554 mph) was reached, setting a new world record for the relative speed between two conventionally wheeled trains.[2]
On June 29, the test trains ran in Haiwei tunnel and conducted a maximum speed of 420km/h for a single train a 840km/h of relative speed.[3]
2024
[edit]On December 29, CRRC hold a media conference in Beijing, China, officially released the two prototypes of CR450 family EMUs, CR450AF-0201 and CR450BF-0501[4]
2025
[edit]The CR450AF is expected to enter regular service in 2025, by the end of the 14th five-year plan.[5]
Design
[edit]In comparison with the previous generation (CR400BF), it is reported that the train is 10% lighter[6], reduced drag for 22%[6] consumes 20% less energy[7] and has a 20% improved braking performance.[7]
Interior
[edit]There are four classes of seating classes on board the CR450BF: Second Class, First Class, Premium First class and Business Class.[8]
Second Class has 482 seats in a 2-3 layout, similar to other Chinese EMUs and carriages.[9] First Class has 28 seats in a 2-2 layout. Compared with second class, the seats are made of leather and offer improved comfort with more width and legroom.[9] Premium first class has 24 seats in a 2-2 layout, and debuted in 2023 on previous CR400 trainsets. Compared with first class, it offers greater legroom and features a footrest.[10]
The business class cabin has undergone various redesigns, consisting of three different types of seating configurations: a 6-seat classic business class setup, a business suite that accommodates six individuals, and a multi-purpose suite that offers more privacy.[11]
Variants
[edit]CR450BF-0501 Prototype
[edit]The first trainset to be built, the CR450AF-0201, was first rolled out on November 26, 2024. It is designed for testing and qualification purposes.[12]
