Montour Railroad Tunnels

The Montour Railroad had a total of four tunnels, three constructed in 1913-1914 for the Mifflin Extension, and one (Jeffreytown) constructed in 1926 during a realignment to eliminate sharp curves between Cliff Mine and Imperial. Three tunnels (all but Peacock) still remain and are utilized by the Montour Trail, a 46 mile recreational rail-trail around the southwest side of Pittsburgh.
