The tanker, which was carrying about 8,500 gallons of gasoline, burst into flames after colliding with a car on McCarter Highway in Newark at about 1:30 a.m. Thursday. Fire officials say no one was injured.
The highway is adjacent to Amtrak's Northeast Corridor rail line. Amtrak trains are running with minor delays while crews repair damaged signals and overhead wires.
New Jersey Transit spokesman John Durso Jr. says the commuter railroad's Northeast Corridor and North Jersey Coast Line trains are operating with delays of up to 60 minutes. Raritan Valley Line service has resumed.
Westbound trains are not stopping at Newark Airport.
Police are investigating the crash.
