East Slope, West Slope and Horseshoe Curve Operations

Conrail operated trains over the world famour Horseshoe Curve during its entire existence. This engineering marvel is a national historic landmark, and is known to railfans around the world.  

The 'curve changed over time. Slimming from 4 tracks when Conrail started to 3 in the early 1980s, and many of these views are of things that are gone, or are from locations you shouldn't go to (due to more stringent enforcement of tresspass laws).

This gallery is a way to visit the area and see how Conrail's ops changed, and how they've stayed the same.  Included are photos from the main helper district over the Allegheny Mountains between Conemaugh and Altoona, PA.
