This stretch of track, originally laid by the West Philadelphia Railroad in 1835, is the tail end of a horseshoe curve that was built to better able the locomotives of the time to handle the steep grade between Overbrook and Wyndmore, PA. The route itself is a bypass of the cable operated plane know as the Belmont Plane that was originally built to get from Philadelphia to Ardmore. Click on the map to the left to see the curve.
