The western extension to Metro Line 12 of Shanghai will go into service by the end of the month.
The extension features 16 stations, and the whole line now connects with every other on the network, except 5 and 16.
The system operator said the service will help to ease the pressure on lines 1 and 9 during peak hours.
To make the line even more appealing to passengers, all station platforms on the new extension have been fitted with air purifiers, the company said.
