The Mahanoy and Broad Mountain Railroad, predecessor of the Reading Company opened the Mahanoy Plane on July 16, 1861. The Plane traversed Broad Mountain between the boroughs of Mahanoy Plane and Frackville. With a pitch of 28 degrees at its steepest point, the plane rose {{convert|524|ft|m}} over a distance of {{convert|2460|ft|m}}. A {{convert|2500|hp}} engine could hoist a three car trip, equivalent to 200 tons in three minutes. After a fire in 1886, new {{convert|6000|hp}} engines were installed. These were supposedly the most powerful engines in the world, later surpassed only by the engines operating the locks on the Panama Canal. Approximately 800 to 900 railroad cars passed over the plane every twenty-four hours. The Mahanoy Plane ceased operation on February 27, 1932, due to the decline of Anthracite and the much easier route through the Mahanoy Tunnel. Foundations are all that remain and there are currently no plans of historical preservation or restoration.[1] On September 8, 2007, the Pennsylvania Historical & Museum Commission erected a historical marker noting the Mahanoy Plane's historic importance.[2] References1. ^{{Citation | last = Society for Industrial Archeology | year = 1979 | title = A Guide to the Industrial Archeological Sites in the Pennsylvania Anthracite Region}} 2. ^{{cite web | title = PHMC Historical Markers | work =Historical Marker Database | publisher = Pennsylvania Historical & Museum Commission | url =http://search.pahistoricalmarkers.com/ | accessdate = December 30, 2013}} 8 : Rail infrastructure in Pennsylvania|Reading Company|Railway lines opened in 1861|Railway lines closed in 1932|Pennsylvania state historical marker significations|1861 establishments in Pennsylvania|Railway inclines in the United States|1932 disestablishments in Pennsylvania |
