 After the Knox segment was embargoed, the southern terminus became what was known as North Clarion Junction, where there was a fibreboard plant and a wye, the tail track of which had been the P&W's line across to the east side of the Clarion River to the borough of Clarion (county seat of Clarion County).This branch was discontinued at around the time the B&O purchased the P&W.The bridge over the Clarion River needed replacement and the railroad requested that the town help with funding the project.
