The CR450 Electric Multiple Unit (EMU) has successfully completed the design of its prototype and rolled off the production line. Boasting a test speed of up to 450 kilometers per hour and an operational speed of 400 kilometers per hour, it has secured its position as the world's fastest high-speed train. Equipped with permanent magnet traction motors, the CR450 EMU has undergone more than 40 intricate scenario simulation tests designed to replicate extreme operating conditions. The Research and Development (R&D) team will now embark on a series of line tests and assessments, with the anticipation that all tests will be concluded within the next two years.

The CR450 EMU comprises two prototypes: the CR450AF and CR450BF, manufactured by CRRC Sifang and CRRC Changchun, respectively. It features an 8-car formation, consisting of 4 motor cars and 4 trailer cars. To achieve commercial operation, China Railway will conduct rigorous testing at speeds both below and above 200 kilometers per hour on circular test tracks and unopened high-speed rail lines. Additionally, a comprehensive 600,000-kilometer assessment will be carried out to ensure the train's reliability and performance.
