Northbound traffic on Route 65 was rerouted this morning from the Quaker Village Shopping Center entrance in Leetsdale after an unknown vehicle, possibly a train, brought down live wires, borough police reported.

Leetsdale police said authorities weren't sure if a tractor-trailer pulled down low-hanging wires before a Norfolk Southern train struck them. The downed wires fell across 65 and the train tracks, taking out the Subway restaurant sign at Village Drive in the process.

"We can't confirm whether it was a train or a truck that knocked them down," said Leetsdale police Sgt. Dan Raible.

Police redirected traffic for about 45 minutes until a Duquesne Light Co. crew could clear the wires from 65.

None of the wires were sparking or arcing, police said, and no one was injured.

Edgeworth police assisted.
