Several tanker cars from a freight train derailed at a northeastern Philadelphia intersection, but no leaks or injuries were reported.
Conrail spokesman John Enright said the derailment involved three cars and occurred just outside a rail yard in the Port Richmond section shortly after 3 a.m. Wednesday.
He said the cause was unknown and the tanker cars were carrying acetone, a flammable liquid, but there were no leaks.
Enright said busy Aramingo Avenue would be blocked until the cars could be re-railed, probably after rush hour.
Motorists were told to expect detours and advised to avoid the area.
