Line 11 of Suzhou Metro, which connects with Shanghai's Metro Line 11 at Huaqiao Station, started trial operation without passengers on Wednesday.
The 41.27-kilometer Suzhou line has 28 stops between Weiting in Suzhou Industrial Park and Huaqiao in Kunshan, a county-level city near Shanghai.
Between Suzhou and Shanghai, the line runs through Kunshan's downtown area, economic center and technological zone as well as the Yangcheng Lake area. The lake is popular for its hairy crabs.
It also connects to Suzhou Metro Line 3, which runs across the city.
Passengers can change to the Shanghai Metro at Huaqiao, which is the Shanghai Line 11's terminal station at one end. At the other end, Line 11 terminates at Shanghai Disney Resort.
