All Amtrak services between New York Penn Station and Boston South Station have been suspended for the remainder of Saturday, the company said, citing power outage issues.

Amtrak said in a service update posted to its website at 3:30 p.m. ET Saturday that trains would be canceled due to a “a malfunctioning circuit breaker” that has caused a widespread power outage on all of its tracks stretching between Penn Station and New Haven Union Station in Connecticut.

The company said it would continue to update customers as new information becomes available.

Those with affected train tickets will “typically be accommodated on trains with similar departure times or another day,” Amtrak said, adding that the company will waive any additional charges for those looking to change their train tickets due to the outage.

On Saturday morning, the company said all services were “suspended until further notice” citing the power issue. According to the Amtrak Northeast account on X, a number of delays and cancellations were already underway at the time of the morning announcement, and continued throughout the day.

The company had estimated that services would resume around 12 p.m. ET, but kept canceling trips throughout the afternoon, according to updates posted on the X account.

Just before noon, Amtrak suspended all trains originating from Boston and estimated at the time that service would be resumed by 3 p.m. ET.

A record 71 million people were expected to be on the move over the Fourth of July holiday weekend, with an additional 5.7 million travelers compared to pre-pandemic levels, according to AAA. The agency said more than 4.6 million people were expected to travel on trains, buses and cruises.
