In August this year, the Beijing Tianjin inter city railway has completed its 10th anniversary of operation. It has safely sent 250 million passengers, which is equivalent to transporting 36 million permanent residents in Beijing and Tianjin for three rounds, reducing more than 17000 cars passing between Beijing and Tianjin every day, and reducing 1.685 million tons of carbon dioxide emissions.

Who can imagine how difficult it was to open the Beijing Tianjin inter city railway 10 years ago.

"At that time, who would have thought that the high-speed railway would bring such a great change to Chinese people's travel! We builders started almost from scratch, excited and nervous in the daytime, often unable to sleep at night, and had to solve various new problems every day. As we all know, the Beijing Tianjin intercity model will be a model project of China's high-speed railway." In July 2005, the Beijing Tianjin intercity railway with a total length of about 120 kilometers officially started, Zhou Zhaochun, now the chief engineer of the Housing and Bridge Company of China Railway Construction 14th Bureau, was the project manager of Beijing Tianjin Intercity.

At the beginning of this century, China's railway development was highly anticipated: worldwide, high-speed railway has become a booster for economic take-off in more than 10 countries and regions, while China's railway equipment level is only equivalent to the level of developed countries in the 1970s, seriously restricting economic and social development. The construction of steel arteries needs to be faster and faster.

A "conference war" of independent innovation has quietly started around high-speed railway. Nearly 100 professors and researchers, more than 960 senior engineers, and more than 5000 engineering and technical personnel from different industries, colleges, and enterprises participated, which not only integrated high-speed railway into the wisdom of all walks of life, but also led to the take-off of relevant theoretical and technical research.

At 12:35 on August 1, 2008, the first high-speed railway in China, the Beijing Tianjin Intercity Railway, was officially opened to traffic as the C2275 train slowly left Beijing South Railway Station. The Beijing Tianjin inter city railway, which operates at the highest speed in the world, has not only become a new business card of China, but also opened a new era of high-speed railway for China, making China the fourth country in the world to systematically master high-speed railway technology of 300 kilometers per hour.

In the past 10 years, the daily number of trains operated between Beijing and Tianjin has increased from 47 pairs at the beginning to 108.5 pairs now, an increase of 1.3 times. "The Beijing Tianjin inter city railway has really changed the way residents live, work, communicate and travel in Beijing and Tianjin." Li Xueqian, the steward of the first Beijing Tianjin inter city train C2275 and now the conductor of the Beijing Tianjin inter city fleet in Tianjin passenger transport section, witnessed the rapid development of the Beijing Tianjin inter city railway.

The Beijing Tianjin inter city railway is just the starting point for the rapid development of high-speed railway in China. Crossing the northern wind zone, winding Lingnan mountains and rivers, galloping the snowy sea in the northeast, and shuttling through Jiangnan water towns, China's high-speed railway network is becoming larger and larger, the number of trains is becoming more and more dense, and there are more and more "say go trips". By the end of 2017, the operating mileage of high-speed railway in China had reached 25000 km, accounting for 66.3% of the total high-speed railway in the world, ranking first in the world.
