China Railway CR450AF

2020 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". 2023 On June 28, test runs were conducted on the Fuzhou-Xiamen high-speed railway using two trainsets: CR400AF-J-0002, a comprehensive inspection train (CIT) containing a CR450AF intermediate car, and CR400BF-J-0001, a comprehensive inspection train containing a CR450BF intermediate car. During these tests, a speed of was reached, and a relative speed of was reached, setting a new world record for the relative speed between two conventionally wheeled trains. On June 29, test runs through the Haiwei tunnel were conducted. During these tests, a speed of was reached, and a relative passing speed of was recorded. 2025 The CR450AF is expected to be delivered to China Railway in 2025, enter regular service thereafter on existing high-speed lines which limits the operating speed to 350km/h due to line limitations. Future It is expected that in 2026 it will be deployed on the Beijing-Shanghai line. In 2027 it will be deployed on the 292km long Second Chengdu-Chongqing high-speed railway which is expected to be finished by then, where it can reach its designed highest operating speed and shorten the travel time between the two cities to less than 50 minutes. == Design ==

According to CRRC, compared to the CR400AF, the CR450AF: • Is 10% lighter • Has 22% lower drag Unlike other production models, they are hidden under the side skirt of the frame with a enclosure design for better aerodynamic performance and therefore reduce drag for a better energy efficiency, similar to those seen on the Japanese Shinkansen, or the end-car of German ICE 4. Interior There are four classes of seating on board the CR450AF: Second Class, First Class, Premium First class and Business Class. Second Class has 482 seats in a 2-3 layout, similar to other Chinese EMUs and carriages. 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. 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. == Variants ==

CR450AF (Prototype) 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. == See also ==
