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:

JUST about to take the A at 181 when I saw everyone run out of the station for their lives. Something exploded; smelled very chemical-like. — Matt Hawkins (@FortNinety) November 7, 2014

Woman told me a train car caught on fire, then another. People were jumping out and ran onto the tracks, panicking. Sounds like total bedlam — Matt Hawkins (@FortNinety) November 7, 2014

Not sure if anyone was seriously hurt; get the impression that everyone’s shaken but ok. Glad people were able to pry open the sealed doors — Matt Hawkins (@FortNinety) November 7, 2014

Again, sealed cars make zero sense; unless they unlock when the emergency brakes are on… I hope so. Otherwise could cost lives. — Matt Hawkins (@FortNinety) November 7, 2014

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.
