Reasonable development of transportation network PPT, part 2: my country’s high-speed railway
High-speed railway refers to a railway system with an operating speed of 200 kilometers per hour (it is also said to be 250 kilometers). When Japan's Shinkansen system opened in 1964, it was the first high-speed railway system in history to achieve an "operating speed" higher than 200 kilometers per hour. For high-speed railways, in addition to the trains reaching a certain speed standard during operation, the vehicles, rails, and operations all need to be coordinated and improved. High-speed railway technology is an important manifestation of a country's industry and transportation industry
On March 31, 2008, the first domestically produced CRH3 high-speed EMU with a speed of 350 kilometers per hour rolled off the assembly line and entered test operation.
It is the highest speed currently put into actual operation in the world. In fact, China’s high-speed rail speed represents the current high-speed rail speed in the world. As China's first true high-speed railway, the Beijing-Tianjin high-speed railway has been at the forefront of the world since its inception, creating four world firsts in operating speed, transportation volume, energy conservation and environmental protection, and comfort. In just five years, China has surpassed half a century of high-speed railway development in developed countries.
