A subsidiary of the Chinese corporation CRRC, Changchun Railway Vehicles Co., Ltd., has unveiled a new type of bogie for high-speed trains designed to travel at speeds of up to 400 km/h., this is reported by the railway transport news portal Railway Supply.

This reduction in weight allows for a 15% decrease in energy operating costs and approximately a 30% reduction in wheel and rail wear.

Additionally, maintenance costs for both tracks and bogies will decrease by 15% over their service life.

These improvements make electric multiple unit trains more environmentally friendly and energy-efficient.

The company also noted that the maximum design speed for trains using these bogies is 400 km/h.

During testing, these trains have reached speeds of up to 600 km/h.

Liu Zhenfang, Chairman of the Chinese Railways, previously stated that by 2025, the Chinese high-speed rail network will feature the CR450 train, capable of reaching speeds of up to 450 km/h.
