Transit officials say two Manhattan subway cars jumped the tracks about 30 meters north of a station near Central Park. Officials say the 400 passengers on the train were safely evacuated. The cars derailed shortly at about 4:23 p.m. Sunday just north of the 57th Street and 7th Avenue stop on the N train line, which was traveling south from Astoria, Queens, to Brooklyn. Firefighters removed the passengers from the tunnel in about an hour, evacuating them on a "rescue train." Two people reported minor injuries, but didn't require treatment. The cause is under investigation. Most N train service in Queens has been suspended and R trains have been rerouted.
