NORTH BERGEN, N.J. (CBSNewYork/AP) — Both rail tunnels leading in and out of New York City have reopened after a derailment caused delays for passengers this morning.

Amtrak said a machine that does track maintenance derailed in the northbound Hudson River tunnel around 4.25 a.m. That left only one tunnel for Amtrak and NJ Transit trains to use between Manhattan and Trenton.

Amtrak spokesman Cliff Cole said the equipment was removed and the tunnel was reopened by 8:45 a.m.

Amtrak trains were running up to 30 minutes behind schedule until the tunnel was cleared.

NJ Transit’s Northeast Corridor and North Jersey Coast Line trains were delayed up to 60 minutes in and out of New York’s Penn Station.

Midtown Direct trains operated to and from Hoboken until the derailed equipment was moved.
