Chinese train sets record speed for high-speed rail transport

A next-generation train undergoing tests on the Shanghai–Chongqing–Chengdu high-speed railway may become the fastest commercially operated train in the world. It reached a record speed of 453 km/h for this type of transport, reports CCTV+, a TV BRICS partner.

The train is expected to complete 600,000 kilometres of test runs. Its planned operational speed is 400 km/h, exceeding the current global standard of 350 km/h.

Engineers achieved these results through improved aerodynamics and design: the train’s nose was extended from 12.5 to 15 metres, the undercarriage was almost completely enclosed, overall height was reduced by 20 centimetres, and lightweight materials, including carbon fibre and magnesium alloys, were used. According to reports, these innovations reduced aerodynamic drag by 22 per cent and allowed the train to accelerate to 350 km/h in just 4 minutes and 40 seconds – 100 seconds faster than the previous model.

The new-generation train is also noted for its energy efficiency and passenger comfort. It is equipped with permanent-magnet traction motors with a power output of 11,000 kW and an acoustically insulated cabin, where noise levels remain at just 68 dB even at 400 km/h.

Comprehensive trials are planned next year on the Chengdu–Chongqing section. If successful, it will become the world’s first regular commercial high-speed train operating at 400 km/h.
