An electrical fire on Thursday disrupted LIRR and New Jersey Transit service to New York Penn Station, likely caused by a loose panel on an Amtrak Acela train that short-circuited the signal system in the East River Tunnel. The panel detached from train 2155’s second car, causing it to contact the third rail, leading to scorch marks on the train.
On Friday, commuters faced major delays as NJ Transit services were diverted, with LIRR rerouting nearly all traffic to Grand Central Madison. Only one track remained operational through the tunnel, affecting both Amtrak and LIRR services. Repairs on the signal system were completed by Friday evening, with a planned reopening of Platforms 3 and 4 scheduled for Saturday morning. However, uncertainty remained regarding LIRR service as contract negotiations continued.
Officials noted that incidents involving metal debris and third rail issues are common in DC power systems, and this incident specifically resulted from a surge in current that damaged the signaling system.
