Early Monday, Northeast Corridor, North Jersey Coast Line and Raritan Valley Line trains were delayed up to 30 minutes into and out of Newark Penn Station.
The reason? Amtrak signal and switch problems.
Fortunately, the issue was resolved by around 7 a.m.
It's just the most recent trouble for NJ TRANSIT. Recently, three teens were killed walking along the tracks in two separate incidents. Those deaths had officials considering what they could do to improve rail safety.
