CRRC Changchun Railway Vehicles Co., Ltd., a subsidiary of China's leading train maker CRRC, introduced a new type of railway bogie designed for high-speed trains operating at 400 kilometers per hour. This innovative bogie is 20 percent lighter than the standard externally mounted versions and can reduce a train's operational energy consumption by 15 percent. Additionally, it lowers wheel-rail wear by about 30 percent and decreases maintenance costs for both lines and bogies by 15 percent over their life cycle, making electrical multiple unit (EMU) trains greener and more energy-efficient.

Railway bogies are crucial components of trains, supporting the mass of the vehicle, guiding it along the track, and cushioning against shocks from the track during motion. Zhou Dianmai, a senior engineer at the company, emphasized the importance of the bogie, likening it to the "legs" of high-speed trains. He stated, "Trains equipped with these new bogies can run faster, more steadily, and more quietly."
The new bogies are designed to operate at speeds of up to 400 kilometers per hour but can reach maximum speeds of 600 kilometers per hour according to test bench models.
