The Metropolitan Transportation Authority says regular service resumed Monday on Metro-North's Hudson Line, but riders should expect scattered delays of up to 15 minutes.
Service between the city and Yonkers was suspended through the weekend after 10 cars on a freight train derailed near the Spuyten Duyvil station in the Bronx Thursday night.
It made getting around difficult for the 25,000 people who rely on the line on a typical weekday.
Crews are still working to clear the train and rebuild more than 1,500 feet of track.
The MTA says only one track was in use Monday.
"This is a pretty hefty thoroughfare, so I think there was a real emphasis on getting it done but obviously we've got tracks behind me, this is the normal track to the city, so there is some work to do but I think it's great. They move quick," said one Metro-North rider.
The MTA says the derailment occurred at the worst possible location. The train jumped the tracks in a narrow area that fits just two tracks, rather than the typical four. Both tracks were damaged and removing the train and debris was extremely difficult.
"The derailment involved not only cars off the tracks you can see here there’s open garden containers, garbage containers on their side all in an area constrained by the rock cut," said Metro-North President Howard Permut.
Even with the possibility of delays, riders who spoke with NY1 this morning say they're just glad the trains are back.
"I was really nervous on Friday when I knew that it might not run so I'm very happy that it's up," said one Metro-North rider.
"Well I think given the heat and the time of year it's a lot easier to know your day is gonna run smoothly," said another Metro-North rider.
For late night service, shuttle buses are running instead of trains so crews can finish repairing the damage.
