Northeast Corridor train #3850 from Trenton came to a stop in the south tube of the Hudson Tunnel around 3:30 p.m., NJ Transit and Amtrak officials said. Amtrak said the passenger count was 400, but a NJ Transit spokeswoman disputed that number.
Brian Scheckner, who claimed to be on the disabled train, said he and fellow passengers were stuck for nearly three hours. Without power for air conditioning, the temperature had steadily risen and passengers got antsy, he said…
Amtrak, which is responsible for the maintenance of the tracks and equipment in and around Penn Station, said the train was disabled due to an overhead power problem.
