The Metro service on the north-south corridor were disrupted during the office rush on Thursday morning after a man jumped in front of a train at Kalighat station.
The man died.
The incident took place around 10.20am when a New Garia-bound train was entering Kalighat station.
“The man jumped in front of the train. The driver tried applying the emergency brakes but it was too late. We had to take a power block to retrieve him from the tracks,” said a Metro official.
The incident prompted the Metro authorities to run a curtailed service for an hour.
Trains ran between Dakshineswar and Maidan in the north and Tollygunge and New Garia in the south. Trains can take a U-turn and change tracks at Tollygunge and Maidan stations.
Between 10.20am and 11.20am, there were no service between Tollygunge and Maidan. The service on the full corridor resumed after 11.20am, said officials.
The disruption tormented many office-goers. Successive trains were stuck at stations. Even after trains started running on the entire corridor, it took a while for the service to become normal.
The police said the man who jumped in front of the train was Sujit Kumar Sahu, 45, a resident of Arabinda Palli in Behala.
Suicides and suicide bids have for long plagued the north-south Metro corridor. The stations on the east-west line have platform screen doors that prevent suicide bids.
