The train delays in New York last week were caused by a combination of issues, including a malfunctioning circuit breaker, power outages, and a disabled NJ Transit train. These problems led to disruptions in Amtrak and NJ Transit services in and out of New York Penn Station, resulting in significant delays for commuters. The root cause of these issues is attributed to aging infrastructure and a lack of investment in the rail system.
Amtrak attributed the delays to a combination of factors, including extreme heat causing tracks to develop kinks and overhead power wires to sag, a brush fire near the tracks, and a malfunctioning circuit breaker resulting in power loss2. These issues required trains to operate at slower speeds and led to service disruptions.
The Regional Planning Association did not directly describe the relationship between Amtrak and NJ Transit in the provided web search content. However, Tom Wright, head of the Regional Planning Association, mentioned that Amtrak and NJ Transit have generally worked well together on projects like the Gateway Tunnel Project, but the issues facing the rail services come down to "decades of underinvestment."
