Introduction: The work depicts the Zhengzhou-Wan High-speed Railway and Meixi River Bridge in Fengjie, Chongqing, which were built after the Sixth Plenary Session of the 19th CPC Central Committee. With a total length of 8 18km and a designed running speed of 350km/h, Zhengzhou-Chongqing High-speed Railway is an important part of Zhengzhou-Chongqing High-speed Railway, and it is the main channel to build a rapid passenger transport network between southwest China and Central and North China.
Meixihe Bridge has a total length of 688.3 meters, a main span of 340 meters and a maximum height difference of 200 meters. It is the largest through arch bridge on the ballastless track of high-speed railway with a speed of 350 kilometers per hour in China. This work shows that China's high-speed rail technology and bridge engineering have achieved a qualitative leap through the freehand brushwork of ink and wash, and are striding towards the center of the world stage.
China's high-speed railway refers to the high-speed railway built and put into use in China, which is an important transportation infrastructure in contemporary China. Used for high-speed operation of EMU, it can be divided into two types: passenger dedicated railway and high-grade passenger-freight common railway. Its design speed is above 250 kilometers per hour (including reservation), and the initial operation speed of the train is above 200 kilometers per hour.
Greater China chengdu-kunming railway:
This is a heroic railway. More than 300,000 road-building troops fought hard and sacrificed more than 2,000 people, opening the steel artery connecting Sichuan and Yunnan provinces. This is a difficult and dangerous road. Generations of "Cheng Kun people" used a shovel and a pickaxe to keep chengdu-kunming railway open for 50 years.
This is a road to people's happiness, which has been non-stop for half a century and has played an inestimable role in national construction, local development and national unity and progress. Chengdu-kunming railway has been upgraded, speeded up and leapfrogged through electrification, capacity expansion and transformation since it was built and opened to traffic for 50 years. No matter in the past or in the new period, it shows the unremitting struggle spirit of the Chinese nation.
Chengdu-kunming railway is a national railway I-class passenger and freight common line connecting Sichuan Province and Yunnan Province in China, which was completed on June 65438+July 1. 0970. The line starts from Chengdu Railway Station in the north and ends at Kunming Station in the south, with a total length of 1.096 km. It is one of the railway trunk lines in the southwest of China and one of the three horizontal and five vertical railway trunk lines in China. On June 26th, 2022, 65438+February 26th, 2022, the new chengdu-kunming railway was put into operation, and the travel time from Chengdu to Xichang, Panzhihua and Kunming was greatly reduced, reaching 3 hours, 5 hours and 7.5 hours respectively.
