Authorities are on the scene of an overnight freight-train derailment in Port Richmond.
The incident happened on the train tracks crossing Aramingo Avenue near Castor Avenue shortly before 3:15 a.m.
The last three tanker cars of the nine-car train derailed, Conrail spokesman John Enright said.
One car has been re-railed and removed from the scene, and officials are working to re-rail the remaining two cars.
The cause of the derailment wasn't immediately known.
The tankers were carrying acetone, Enright said. Crews investigated and found no leaks, according to the Philadelphia Fire Department.
No injuries were reported.
Motorists should expect delays and detours in the area as the train continues to block the road and emergency responders remain at the scene. Nearby traffic could be disrupted through the rest of the morning.
