Amtrak and New Jersey Transit services were impacted, with rail service between New Jersey and New York's Penn Station suspended. Amtrak President Roger Harris cited a circuit breaker failure and brush fire as causes, exacerbated by high temperatures. Extreme heat can stress infrastructure, causing delays and even derailments. New York City faced a heat advisory, further complicating transit operations. Experts warn that climate change will lead to more extreme weather events, affecting mass transit systems. New Jersey Transit acknowledged the impact on customers and vowed to address the issues. Frustrated commuters expressed hope for improved service, as the situation remains challenging due to ongoing infrastructure problems.
