       Beijing-Shanghai high-speed railway is the world’s longest one-time high-speed railway with the highest standards. It is also the construction project with the largest investment scale since the founding of the People’s Republic of China.  It is one of the "eight vertical and eight horizontal" high-speed railway passages in the national "medium and long-term railway network planning". The construction and operation of the Beijing-Shanghai high-speed railway has promoted the coordinated development of the two economic regions of the Beijing-Tianjin-Hebei and the Yangtze River Delta, greatly improving the convenience for travelers among Beijing, Tianjin, Jinan, Xuzhou, Bengbu, Nanjing and Shanghai. It’s of great significance to China's economic and social development. The Beijing-Shanghai high-speed rail has established a standard system and technical system for China's high-speed railway, supported the rapid development of China's high-speed rail, and created a Chinese high-speed rail brand with advanced technology, safety, reliability, and cost-effectiveness. The high-speed rail represented by Beijing-Shanghai high-speed railway has become a beautiful business card for China.
