A Norfolk Southern "baretable" train crosses the Little Conemaugh River just west of South Fork, PA. This section of the Pennsylvania Railroad follows the grade of the Allegheny Portage Railroad, originally part of the Mainline of Public Works that carried canal boats over the Allegheny Mountains. The original "Big Viaduct" was a single arch bridge and was destroyed by the Johnstown Flood in 1889. PRR rebuilt the bridge following the Flood as a two arch span.
Landscape photography is difficult due to the challenge of combining good light and good scenery. Good railroad photography enters another level of complexity since it requires the first two while there is a train in view.
A continuously growing album of photos that IMHO reveal the awesome and seldom-seen beauty of the railroad world from the dimming of day to dawn's early light! From dusk to dawn, trains roll on! (I'm still finding gems of sunset-to-sunrise surprises!)
