LONG waits on platforms and overcrowded carriages marred the “official” opening yesterday of the Metro Line 16 extension.

“I’ll probably go back to taking the bus if the situation doesn’t improve tomorrow,” commuter Cai Zhen said after waiting at East Zhoupu Station for more than 20 minutes before being able to get on a train.

Cai said she planned to take the new service to Longyang Road and then change to Line 2, which would take her to work.
