An Amtrak work train erupted in flames near New York’s Penn Station on Friday morning, injuring five people and disrupting rail service into midtown for thousands of commuters.

The two-alarm blaze erupted at around 1:30 a.m. when the FDNY received reports of an Amtrak work train car on fire on track 11 in one of the Hudson River Tunnels, according to fire and NJ Transit officials.

Forty-six units and 141 personnel responded to the blaze.

NJ Transit service between Penn Station and Newark Penn Station remained suspended during the rush hour commute on Friday as officials warned commuters to brace for heavy delays and possible cancellations.

Two victims were transported to Bellevue Hospital with serious injuries, the FDNY said. The remaining three individuals refused treatment.

All five victims are transit workers, an FDNY official told reporters, according to 1010WINS.

Overhead wiring was damaged along track 11, which forced the New Jersey Transit and Long Island Railroad to suspend service in and out of the busy Manhattan station.

“Customers should expect significant delays and cancellations on the Northeast Corridor and North Jersey Coast Line, and should work from home if possible or consider alternate travel,” officials said.

“On the Northeast Corridor and North Jersey Coast Line, all operating local service will terminate at Newark Penn Station, where trains will turn around for westbound travel. All Jersey Avenue trains are canceled. For essential travel, please take trains out of New Brunswick Station.”

The transit agency redirected its Midtown Direct service to Hoboken, where passengers holding rail tickets and passes will be transferred to private buses and PATH and taken to the 33rd Street station in NYC.

Amtrak officials told the New York Times service between New Jersey and New York could return by the afternoon. 

Meanwhile, commuters scrambled to find alternative travel options.

Erin Splaine, a 25-year-old engineer trying to get home to Union County in New Jersey, learned when she got to the station that there were no trains. She said she was considering taking an Uber home from Hoboken.

“I mean, it’s annoying, but it’s NJ Transit. We kind of expect it,” she said.

Katherine Acquabello, a 31-year-old editor visiting from California, was trying to get down to the Jersey Shore when she heard there was a fire. She said she might end up taking the ferry.

“So now it’s just more added steps. It just seems like classic New York. There’s always an issue with something.” 

A lengthy line snaked around Moynihan Hall with people trying to get refunds for a cancelled Amtrak train to Washington DC. 

Natasha Stecyk, who is visiting from Los Angeles, was supposed to be on her way to DC with her partner and her two children, but their train was canceled. Tickets on the next scheduled train were going for $1,000, she said.

“We’re trying to see if we can get a standby flight or something to DC because we already checked out of our hotel. So we’re just trying to figure out, like, do we stay another night in the city, or do we do that?” Stecyk said.

Jeremy Bishop, a 43-year-old military officer, traveling with his partner back home to the capital, said that rental cars also jumped to as much as $700.

Many travelers, like Manhattan resident and nurse Sarah Shields, 37, said that the railroads need to do a better job of keeping their customers informed.

“I live in New York, and it’s still confusing for me,” she said. “And people who are coming here are, like, trying to get out to New Jersey to fly home from somewhere, and maybe they don’t speak English. It’s gonna be very confusing for them.” 

LIRR made partial suspensions to its service and redirected 11 of its lines from Penn Station to Grand Central, the agency announced.

Service was reportedly restored just before 6 a.m. 

Crews got the fire under control at 4:05 a.m., and an investigation into the cause is ongoing.
