Enlow Tunnel, a remarkable feat of engineering, was excavated through the hillside in 1926 as part of a realignment initiative by the Montour Railroad. Its construction aimed to eradicate multiple challenging curves in the railroad's original main line. Stretching 575 feet, this tunnel replaced a half-mile section of track that previously wound around the hill alongside Montour Run.
