Which railway connects Beijing and Tianjin with China’s first 350 km/h high-speed service?

The Beijing–Tianjin intercity railway connects the two cities with China’s first 350 km/h high-speed service.

The Beijing–Tianjin intercity railway opened in 2008, shortly before the Beijing Olympic Games. It was designed for rapid regional travel between China’s capital and the major port city of Tianjin, with stations including Beijing South and Tianjin.

The line became a landmark in China’s high-speed railway development because trains were introduced with a scheduled maximum speed of 350 km/h. Operating speeds and timetables can change over time, so a line’s original headline speed should not automatically be treated as its current everyday speed.

This railway is an intercity corridor rather than the much longer Beijing–Shanghai high-speed railway. The two lines both use Beijing South station, which can make their names easy to confuse.
