Commuter rail service from Connecticut to New York City, along with Amtrak service between Boston and New York, was back on schedule Wednesday morning on one of the nation's oldest and most heavily traveled railways.
Limited service resumed Tuesday afternoon.
Beginning with the 3:07 p.m. departure from Grand Central Terminal, Metro-North operated about half of the regular eastbound PM peak service and regular hourly westbound service with the 4:23 PM train from New Haven.
Repair work on tracks that were damaged in last week's train collision has progressed quickly.
Friday's train derailment just outside of Bridgeport injured more than 70 people.
The MTA crews are working around the clock to rebuild 2,000 feet of track, signal system and overhead wires on a section of the New Haven line that serves 30,000 daily riders. Authorities are asking everyone, even drivers, to carpool or work from home if possible.
The National Transportation Safety Board is working to figure out how the derailment happened. Investigators ruled out foul play and are taking a closer look at a fracture in the rails.
"The track team has identified and removed two segments of rail in the area of fracture discussed yesterday, and are sending those to our team in Washington D.C. for analysis," Earl Weener, NTSB Spokesman.
Shuttle trains will run every 20 minutes from New Haven to Bridgeport, there passengers can pick up a bus to Stamford. From there you can get on a train to Grand Central.
If you can use the Harlem line, you're urged to do so. New Haven line tickets will be cross honored.
