Metro-North's Hudson Line is now running in both directions, four days after a freight train hauling garbage derailed in the Bronx.
The railroad says all trains are running with scattered delays of up to 15 minutes until 10 p.m. After 10 p.m., bus service will connect commuters to shuttle train service.
The freight train derailed between stations Thursday night.
The derailment affected service on the line that runs between Manhattan and Poughkeepsie.
The damage was so substantial that only one of two tracks in the area is back in service on Monday. Work will continue on rebuilding the other track before it can be returned to passenger service.
The cause of the derailment is under investigation by the National Transportation Safety Board.
