"There was a very loud explosion that shook the train," a commuter said. A fire erupted on Amtrak work trains in a Hudson River tunnel between New York and New Jersey early Friday, suspending Penn Station service for NJ Transit and Long Island Rail Road commuters. LIRR service resumed by the morning rush hour, but the NJ Transit suspension into Penn Station lasted through mid-day Friday. Around 1 p.m., NJ Transit said it was resuming trains into and out of Penn Station, but it warned that commuters should still be prepared for delays and cancelations. Two Amtrak work trains collided in the Hudson River tunnel at about 1:25 a.m., impacting the electrical system and igniting a fire, said Janno Lieber, head of the Metropolitan Transportation Authority. Several workers were injured, according to ABC New York station WABC. A passenger on a train photographs a fire on a maintenance vehicle in a tunnel under Penn Station in New York City, May 29, 2026.…
