[Update Below] The subway station at 181st Street in Manhattan is being evacuated after the station filled with smoke this afternoon. According to FDNY, a fire broke out around 2:20 p.m. at the 181st Street station near Fort Washington Avenue. Both police and FDNY confirm that the station was filled with smoke, which cops say was caused by a "fire coming from the track area." There are no reports of injuries yet, and FDNY is current at the scene.

There have been a lot of frantic tweets from people who were aboard the A train there.

Matt Hawkins has the most detailed report from the scene so far:

The MTA says they are investigating, and A trains are suspended in both directions between 168th and 207th Street.

Update: Local businesses tell us they have seen firefighters swarming the area. A worker at the Great Wall Chinese Restaurant told us the restaurant "smells something bad, like burning, fire." Ernie, who works at Nuñez Hardware, said that firefighters told him something happened on the tracks, but wouldn't elaborate.

Update: FDNY officials tell us that the fire is under control as of 3:12 p.m. They say it was started by a transformer within the station, but could not confirm whether there were any explosions, or if the train at the station caught fire. There were no injuries, and they are still at the scene.

MTA gave this statement about the incident:

At approximately 2:20pm, FDNY responded to a smoke condition at the 181 St that appears to have emanated from a transformer at that location. The incident DID NOT involve a train and as per FDNY, there is no indication of any kind of explosion. Power was turned off by FDNY and the smoke condition is under control. Northbound A and C trains are terminating at 145 St. There is no A service between Inwood-207 St and 145 St. at this time. Continue to monitor service status on our homepage for the latest on service.
