A fed-up straphanger went off the rails on social media over recent packed city subway cars, trashing the MTA for its alleged shoddy service and posting videos of stuffed trains in the midst of the coronavirus pandemic.

“We’re all going to f–king die,” the woman says in a YouTube clip shot Friday. “Packed. And then you continue to say 6 feet away from each other. How is this possible?

“How is this possible with the MTA?” the woman, who described herself as an essential health-care worker who commutes from the Bronx to Queens, said. “Last week, the trains were empty. And now, this week, it’s packed. This is (a) death trap, and we have to go to work. And you have people waiting 20 minutes, a half-hour in between, because MTA workers are sick.”

“Anxiety is not the word,” she says in another video. “This is day three that is packed. We’re supposed to be 6 feet away from each other, and look at [the] MTA. … People are dying.”

The footage shows packed subway trains and platforms, in some cases shoulder-to-shoulder with each other. At one point, a man is heard in the background selling drugs inside the crowded car.

The MTA has been hard hit by the COVID-19 bug, with at least two workers dying from the virus and at least 156 others testing positive — while another 1,181 have self-quarantined, officials said.

“If you’re short-staffed, then you should close the MTA down and people stay at home,” the straphanger said. “This is ridiculous.

“Gov. Cuomo, how serious are you?” she said. “The MTA has to be addressed.”
