A westbound Amtrak Keystone rounds the tight bend through Narberth, PA, ducking the Narberth Avenue bridge that was built back in 1902. The bridge, rehabilitated in 1947 is currently, a year past due for demolition. Click here to see an old photo of the bridge (which is nearly identical in style to the now pedestrian only bridge at Berwyn), and here to see the proposed new design set for 2021.
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, a bypass of the cable operated plane know as the Belmont Plane that was originally built to get from Philadelphia to Ardmore.
