Connecting cities, changing lives

50,000-km milestone

On Friday, with the opening of the Xi'an-Yan'an high-speed railway in Shaanxi province, China's high-speed rail operating mileage surpassed 50,000 kilometers, the world's largest operating mileage, surpassing the combined total of all other countries, according to the China State Railway Group, the national railway operator.

The milestone reflects more than the completion of a single line. It marks the maturation of a nationwide network that now reaches almost all of China's major cities, turning what were once long-distance journeys into routine trips.

Before 2008, China's high-speed rail network was still in its early exploratory stage, with lines such as the Qinhuangdao-Shenyang intercity line, which operated at a speed of 200 km/h, testing the possibilities of high-speed travel.

In 2008, a major milestone was reached with the opening of the Beijing-Tianjin intercity railway, China's first high-speed line designed for 350 km/h service.

The pace of expansion accelerated rapidly in the following years. In 2011, the Beijing-Shanghai high-speed line commenced operations, and by 2012, the Beijing-Guangzhou line was fully connected. By then, the network had grown to nearly 10,000 km.

Currently, the high-speed rail network covers almost all major cities in China. More specifically, it serves 97 percent of cities with urban populations of over 500,000. High-speed rail carries 80 percent of all railway passengers in China, dominating medium — and long-distance travel. On an average day, 9,346 high-speed trains are in operation, making around 9.36 million passenger trips across the country — more than the 8.3 million population of New York City, the most populous city in the United States.

During peak travel periods, daily train services can exceed 10,000, transporting more than 16 million passenger trips, greatly alleviating pressure during peak periods such as the Spring Festival travel rush.

As the network has expanded, travel time between cities has been dramatically reduced. Within major city clusters, destinations within a 500-km radius can now be reached in one to two hours, making frequent, commuter-style travel possible. Cities up to 1,000 km apart are connected within four hours, allowing for same-day round trips, while journeys of up to 2,000 km can be completed in about eight hours.

These time savings have helped redraw the country's economic and social map, bringing cities closer together and encouraging the flow of people, information, and capital across regions.

For example, the Beijing-Shanghai high-speed railway covers about 1,318 km in roughly four and a half hours. The Beijing-Guangzhou line, spanning 2,298 km, can be traveled in around eight hours. Even short-distance routes have been transformed: the Beijing-Tianjin intercity line, just 120 km long, allows commuters to move between the two cities in about 30 minutes.

Together, these connections form the backbone of China's "eight vertical and eight horizontal" high-speed rail network — a medium and long-term national plan designed to link the country's major north-south and east-west corridors and support coordinated regional development.
