A packed No. 7 train was evacuated during Monday's morning rush because of a smoke condition in Queens that caused a two-hour suspension on the busy line and lingering delays, the MTA said.
Service between Times Square and Queensboro Plaza was restored around 10:30 a.m., about two hours after it was shut down over a train that became disabled amid reports of smoky conditions near the Vernon Boulevard - Jackson Avenue stop, the FDNY says.
The MTA says the train stopped as if someone had pulled an emergency brake, though it's not clear if a brake was pulled. Authorities then found one of the cars' contact shoes, which connect to the electrified rail, was disabled on the protection board above the rail, creating the smoke condition.
Power to the line was cut and a rescue train took straphangers to Grand Central Station.
No injuries were reported.
