A man jumped in front of an oncoming northbound 6 train in Manhattan today, according to the MTA.

The transit spokesperson tells us the incident happened at 2:56 p.m. at the 23rd Street platform. The man was alive when he was removed from the tracks, and the FDNY transported him to Bellevue Hospital in an unknown condition.

One witness sent us the following account, via email:

We were on the section between 14th and 42nd, and just as we pulled in to 23rd I felt a reasonably large jolt. I thought it was a track bump or the driver slowing down too quickly. We waited in the station for a few minutes. They didn't open the doors, which was unusual because usually they wait at most thirty seconds to open them. Then an MTA employee crossed from the previous car to our car and used his key to unlock one of the doors. Half of us filed out (I figured I'd just walk) and the other half stayed inside. But the train won't be moving for a while, that's for sure.

As I got out I heard a witness describe a man running in a straight line perpendicular to the track as the train pulled in. The police came and two officers ran down the steps to interview witnesses, and asked others to step aside. A number of additional emergency vehicles responded, including ambulances and police.

There are a number of service changes currently in place—notably, northbound 6 trains are running express from 14th Street-Union Square to Grand Central-42nd Street, some northbound 4 and 5 trains will terminate at Wall Street, some northbound 5 trains will run local from Franklin Avenue to Atlantic Avenue-Barclays Center, and some northbound 5 trains will run on the 2 line from Nevins Street to 149 Street-Grand Concourse. You can expect delays on northbound 4, 5, and 6 trains.

We will update when more information becomes available.
