The entry and exit gates of metro rail networks at containment zones will remain shut, and waiting time will increase to 5-7 minutes as trains will be sanitised at turnaround points. These are some of the guidelines the centre has issued as part of its Unlock4 plan to restart metro trains from September 7 after months of lockdown amid the coronavirus crisis. Passengers are encouraged to use the coronavirus tracker app Aarogya Setu. "Initially, we will open only one line and the operating hours will be 7 am to 11 am and 4 pm to 8 pm," Delhi Metro Rail Corporation chief Mangu Singh said.
