Train traffic to and from New York's Penn Station began to clear up Wednesday morning as Amtrak finished repairs on a rail tunnel where a New Jersey Transit train derailed a day earlier.
The derailment led to service shutdowns and delays for Amtrak, New Jersey Transit and Long Island Rail Road trains. Amtrak owns the tracks used by other train operators and is responsible for all repairs.
Amtrak spokesman Cliff Cole said while tracks are fully functioning, riders should still expect residual delays.
"Things do get backed up and that's where we stand now. Everything's back open, but it's going to take a while to relieve the congestion," Cole said.
The day started with 30- to 60-minute delays on Northeast Corridor and North Jersey Coast Line trains. As of 11 a.m., delays on those lines had decreased to 10 to 15 minutes.
