Fire that caused Penn Station commuting nightmare likely sparked by debris from new Amtrak Acela

Key Points:

• An electrical fire that disrupted LIRR and NJ Transit service to New York Penn Station was likely caused by a loose metal panel on an Amtrak Acela train making contact with the third rail inside the East River Tunnel.
• The panel, detached from the second car of Amtrak train No. 2155, shorted out the signaling system near a rail switch controlling tracks 3 and 4, leading to service outages.
• As of Friday, only one track was operational in the East River Tunnel due to ongoing repairs on track No. 2 from Hurricane Sandy damage, compounding the disruption.
• Amtrak completed signal system repairs and planned to reopen tracks 3 and 4 by Saturday morning, but LIRR service through the tunnel remained uncertain amid ongoing union contract negotiations.
• The incident caused significant commuter delays, with NJ Transit diverting trains to Hoboken Terminal and most LIRR traffic rerouted to Grand Central Madison, potentially extending disruptions into Saturday.
