As the power grid collapsed at around 1 PM, Delhi Metro trains stopped on tracks, some inside tunnels, due to non- supply of power and passengers stuck in the trains were evacuated immediately.
Nine trains stopped inside tunnels after power failure but they were brought to the near-by stations and all passengers were evacuated.
The services, which were suspended a little after 1 PM was restored at around 3 PM with minimum frequency after partial restoration of supply from the Northern Grid.
As the grid failed, Delhi Metro officials closed down all stations and evacuated passengers from the premises with help from CISF personnel, who guard the installations.
Public announcements were made at stations about the power failure and suspension of services. People who were stuck inside the trains narrated their tale of woe after they were brought to stations and evacuated.
"Partial services restored on all lines with a frequency of ten minutes to begin with from 1450 hours," a Delhi Metro spokesman said.
Yesterday, Metro services began an hour late and services were affected for hours due to failure of the Northern Grid.
Passengers today alleged that trains stopped on tracks and they were not aware of the power failure.
