Reply to "My Favorite Railroad Bridge"

My favorite Railroad Bridges are both part of the Philadelphia & Thorndale (P&T) Branch of the Pennsylvania Railroad.  This is the Low Grade Freight Line that Parallels the mainline (Modern day Keystone Corridor)  via a flying junction at the helper yard in Thorndale, PA to Glen Lock Interlocking and connected there to the Trenton cutoff. It was double tracked, built around 1906 and heavily engineered with these bridges and deep cuts and fills to allow fast fright to pass with very little grade or curve and free up the mainline traffic for commuter service. It was later electrified with the rest of the Pennsy in the 30s.  This is the Bridge that spans the Brandywine Creek in Downingtown  (Where I've lived my whole life).  It has no official name or even builders plates but I know it as the Trestle Bridge or the High Bridge.   

Unfortunately it was retired from use by Conrail in the late 80s so I have never seen a live train go over it I think of a GG1 or a Boxcab pulling a late night coal drag with the Pantographs sparking and the headlights shining.  It is pretty interesting to go up there and bike across these days and my recently increased interest in everything train related and wanting to start an O Gauge empire partially stemmed from a recent trip.

My Second Favorite is only miles up on the same line and is the Whitford Bridge which is a flyover of the mainline and was once featured as PRR Calendar art. It's pretty massive up close as there is a current Septa stop right under it's footing. I don't know if it's true but I read somewhere its suppossed to be the longest span single arch truss in the world (or maybe was when built).
