Speed, comfort, services, and safety in one bullet train
Almost all HSR trains, track and service are owned and operated by the China Railway Corporation under the brand China Railway High-speed (CRH). The China Railway High-speed (CRH) high-speed train service was introduced in April 2007 featuring high-speed train sets called Hexie Hao (simplified Chinese: 和谐号; traditional Chinese: 和諧號; pinyin: Héxié Hào; literally: "Harmony") and Fuxing Hao (simplified Chinese: 复兴号; traditional Chinese: 復興號; pinyin: Fùxīng Hào; literally: "Rejuvenation") running at speed from 250 km/h to 350 km/h on upgraded/dedicated high-speed track. The Beijing-Tianjin Intercity Rail, which opened in August 2008 and could carry high-speed trains at 350 km/h (217 mph), was the first passenger dedicated HSR line. High-speed rail (HSR) in China is the country's network of passenger-dedicated railways designed for speeds of 250–350 km/h (155–217 mph). It is the world's longest high speed railway network and is also the most extensively used. By the end of 2018, HSR extended to 30 of the country's 33 provincial-level administrative divisions and reached 29,000 km (18,000 mi) in total length, accounting for about two-thirds of the world's high-speed rail tracks in commercial service.The HSR building boom continues with the HSR network set to reach 38,000 km (24,000 mi) in 2025.
Japan's bullet train 2020

Alfa-X is the E956 Series The next generation of Shinkansen bullet trains will begin testing next year. The state-of-the-art ‘Alfa-X’ is expected to travel faster than 400 km/h (almost 250 mph!) and will have a range of groundbreaking features. The new bullet train will have an aerodynamic, 22-meter nose longer than any train’s in history, improved traction control, and will be made from ultra-light materials. It has also been designed to run almost silently with maximum comfort for passengers. East Japan Railway Co. unveiled a test car of the next-generation ALFA-X shinkansen, expected to operate at a speed of 360 kph, to media Wednesday in Kobe.
Japan's bullet trains in snow
To keep the rails free of snow and ice in the cold and high-rainfall
season sprinkler systems have been installed to meet the high quality
standards of the Shinkansen railway network. Up to now, the pipelines
mentioned were made of steel. Corrosion in the steel pipelines is caused
by the seasonal system stop during the warm summer time which in
conclusion caused a malfunction of the deicing when it was needed.
For the new train section Tokyo - Shin Aomori high quality PE 100
E-fittings and special components from AGRU have been used in order to
fulfil the stringent requirements in this installation. Additional
expansions were installed only with PE 100 piping systems whereby
products of AGRU have provided a very important contribution.
For the sprinkler system at the Shinkansen highspeed railway track AGRU
E-couplers in the dimensions OD 110 mm to OD 400 mm were applied because
of the easy and safe installation at the rail track. Furthermore
moulded AGRU sweep bends OD 125 mm to OD 400 mm were applied to ensure
excellent flow characteristics and high pressure ratings of the
installed piping system.
the Tōkaidō Shinkansen often experiences heavy snow in the area around
Maibara Station in winter. Trains have to reduce speed, which can
disrupt the timetable. Sprinkler systems were later installed, but
delays of 10 to 20 minutes still occur during snowy weather.
Additionally, tree falls related to excess snow have caused service
interruptions. Along the route of the Jōetsu Shinkansen, winter snow can
be very heavy, with snow depths of two to three metres, so the line is
equipped with stronger sprinklers and slab track, to mitigate the
effects of deep snow.
