F train stuck underground in Lower Manhattan as commuters bemoan on social media

LOWER MANHATTAN (WABC) -- Claustrophobia, panic and heat exhaustion.

It was another nightmare of a commute for New Yorkers sick and tired this year of nightmare commutes.

This time, a southbound F subway train was stuck in Lower Manhattan for about 45 minutes.

As time went on, there were no announcements about what was going on and passengers say they were getting nervous.

The train had to be pushed into the Broadway-Lafayette Station just after 7 p.m. on Monday.

Social media was ablaze with pictures of doors closed with no air conditioning inside and windows steaming up.

The incident is now under investigation by the MTA.
