China launched a next - generation train undergoing tests on the Shanghai - Chonqing - Chengdu high - speed railway currently under construction that will run in an east - west direction largely parallel to the Yangtze River, connecting the cities of Shanghai, Nanjing, Hefei, Chongqing and Chengdu may become the fastest commercially operated train in the world.
As reported CCTV+ , a video news agency specializing in video on demand based in Beijing belonging to the state - owned China Central Television televised news network, China’s CR450 high - speed train set a record speed of 453 km/h for conventional rail transport during recent trials and is faster than its predecessor, the CR400, which reached 420 km/h in tests.
This new train setting new speed records while promising faster, safer, and more efficient travel in China and is setting fresh benchmarks in rail technology, is expected to complete 600.000 kilometres of tests runs and its planned operational speed is 400 km/h, exceeding the current global standard of 350 km/h.
Comprehensive trials are planned next year on the Chengdu - Chongqing section and if successful, it will officially become the world’s first regular commercial high - speed train operating at 400 km/h.
To achieve these results in terms of speed performances, Chinese engineers actively worked 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 innovative operations reduced aerodynamic drag by 22% 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 train is equipped with advanced permanent - magnet traction motors, and over 4.000 sensors for real - time monitoring boasting a power output of 11.000 kW and an acoustically insulated cabin, where noise levels remains at just 68 dB even at 400 km/h.
This next - generation train is also noted for its energy efficiency and comfort expanding passenger service space by 4% compared to previous models, and an over - the horizon system has been added to improve the recognition of emergency situations, and is expected to start commercial operations as early as 2026.
