Two SEPTA commuter trains ply the Northeast Corridor early one morning, one southbound, the other north, stopping at multiple stations along a densely populated stretch of track between Prospect Park and Darby, PA. The Pennsy did not elevate its ROW here, necessitating 7 overpasses and 4 underpasses along a 4 mile stretch serving 7 unique stations.
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!)
