It's July 1980 and we're at Bennington, PA deep in the mountains west of Altoona watching a Conrail freight work its way to the summit at Gallitzin. We camped near this location for two nights. In this era, all four mainline tracks were still intact; today there are three. Those distinctive Pennsylvania railroad position light signals can still be found, but are being replaced with more modern types.
Bennington is famous in railroad history as the site of the 1947 wreck of the Red Arrow passenger train. The Red Arrow exited the tunnel at Gallitzin heading downgrade, but thick winter fog made it difficult for the Engineer and Fireman to know their exact location and their speed gained as they came downgrade. The Arrow derailed on Bennington Curve a short distance behind this freight and the train spilled over the embankment.
