Amtrak officials said passengers should be prepared for delays of up to 50 minutes during rush hour as crews continue repairs on an area of track damaged following Monday’s derailment of a NJ Transit commuter train.

Amtrak expects to run trains on a modified schedule through Thursday, according to a service alert issued by the passenger railroad. Officials said customers arriving or departing from New York’s Penn Station, may experience delays of up to 50 minutes during rush hour and 25 minutes during non-rush hours. Passengers with reservations should check with Amtrak before heading to the station.

Because of the reduced track capacity, some Northeast Regional trains will run on a modified schedule with fewer trains between Washington, D.C. and New York. To accommodate passengers affected by the temporary schedule change, Amtrak will provide some additional stops in Delaware, Pennsylvania and New Jersey.

Amtrak’s Empire and Keystone service also will run on modified schedules with some reduced frequencies.

Long distance trains that travel to and from the Northeast Corridor will maintain regularly scheduled service.

Five people were injured when three cars of a NJ Transit commuter train derailed around 9 a.m. Monday, just as the commute was ending. It was the second derailment at busy Penn Station in less than two weeks. On Mar. 24, an Amtrak train derailed causing delays up and down one of the country’s busiest rail corridors.

Rep. Donald M. Payne, Jr. (D- New Jersey), a member of the Transportation and Infrastructure Committee said that the service disruptions only serve to underscore the importance of infrastructure investment.

“Our nation’s aging public transit systems, particularly those in the northeast, are in dire need of federal investment,” Payne said in an emailed statement. “Every day that passes without these investments increases the likelihood of derailments like the ones at Penn Station that injured passengers and caused massive and ongoing service disruptions.”
