NJ Transit and Amtrak services faced major delays due to a power issue causing disruptions into rush hour in New York Penn Station. All power was restored by 5:30 p.m. and services between New Haven and Philadelphia resumed, but significant delays were expected due to backed up rail traffic and single-tracking. The disruption was caused by a malfunctioning circuit breaker and a brush fire in Secaucus. Service eventually resumed, with delays of up to 60 minutes expected. NJ Transit tickets were cross-honored by other transportation services. Amtrak trains were terminated at Philadelphia or Newark. PATH also experienced network connection issues but services resumed to normal. Amtrak had previously warned of delays due to high temperatures in the region.
