Subway Train Derails in Brooklyn in 2nd Such Episode in a Week

A subway train derailed in Brooklyn on Wednesday afternoon, the police said. It was the second derailment in New York City’s mass-transit system in less than a week.

The train, a northbound F, went off the tracks between the West Eighth Street and Neptune Avenue stations in Coney Island shortly before 12:30 p.m., the police said. No injuries were reported in the immediate aftermath of the derailment and the cause was being investigated, according to the police.

Service on the F line was partly suspended in Brooklyn as a result of the derailment, the Metropolitan Transportation Authority said.

The episode on Wednesday came six days after a No. 1 train carrying 300 people collided with an out-of-service train on the Upper West Side of Manhattan because of confusion over which train had the right of way. Both trains derailed as a result, and more than two dozen people were injured.

None of the injuries in the earlier derailment were life-threatening, officials said. Full service was not restored on the affected lines — among the most heavily used in the busiest mass-transit system in the United States — for nearly three days. Investigators have indicated that human error was to blame for the collision.

This is a developing story and will be updated.
