Not that a subway disaster is even newsworthy at this point, but an F train had to be taken out of commission at 23rd Street for a "smoke condition" just a few minutes ago, and now there are some fun service changes and delays.

Straphanger Polly Mosendz says she was onboard a southbound F train at around 5:34 p.m. when it stopped suddenly, eventually ejecting riders at 23rd Street. "I was on the F train headed downtown. At 23rd we heard a loud thud. I thought we hit someone or something, but then we started smelling smoke." She says the conductor got out of the train to check the tracks: "He says he saw flames. Then there was a whole bunch of smoke, and then they told us train was stalled," Mosendz said.

Mosendz says there was quite a bit of smoke in the tunnel, and her conductor believed there was an electrical fire on the tracks:

The FDNY says they responded to reports of a "smoke condition" at 23rd Street at around 5:35 p.m. It's unclear if there was actually a fire:

The MTA says thanks to a train with "mechanical problems at 23 St," southbound F and M trains are running express from 34 St-Herald Sq to W 4 St-Washington Sq, and some southbound F trains are rerouting along the E line from Jackson Hts-Roosevelt Av to Court Sq, and then on the G to Bergen St. Riders on the BDF and M trains can expect delays.

At least it's Thursday.
