NJ Transit spokeswoman Courtney Carroll says Train 3705 broke down just outside the Hudson River rail tunnel around 7 a.m. There's no word what caused the problem.
The train was pulled back to the station by 7:20 a.m. and there are residual delays on the Northeast Corridor and North Jersey Coast Line.
Midtown Direct trains have resumed a normal route after being diverted to Hoboken.
