"Significance: "Because Pennsylvania has few low-lying areas, the Darby River Bridge is one of a limited number of movable railroad structures in the state, and even more rare as an overhead-counterweight bascule bridge." [HAER_data]

These are the Darby Creek Railroad Bridges in Greater Philadelphia, PA.  They are a pair of bascule bridges that were built in 1917 and carry former PRR railroad lines over Darby Creek.  Photo is courtesy of HistoricBridges.org.
[Actually, the northern bridge carried the Reading Railroad.]

I got another Historic Bridges photo since Elaine Deutsch caught the Pennsy bridge in the closed position on Nov 3, 2014. Since there is more boat traffic than train traffic here, most photos catch the Pennsy bridge in the open position. Conrail abandoned the Reading route east of Eddystone, so that bridge is always up.

Pennsy was north of Reading at Ridley Creek, but south of Reading at Darby Creek.

B&T (link at the top of the page), this webpage has a nice history as well as 26 overview photos.

Since the Reading bridge was abandoned soon after Conrail was formed in 1976, it still has its original interlocking machine and signaling pipelines. (The Pennsy bridge was converted to remote control in 2005.) The position-light blog has a lot of photos of the details of the Reading signaling equipment including these three photos.

Abandoned posted five photos with the comment:
The Darby Creek Bridges consist of two bascule spans crossing Darby Creek near Chester, Pennsylvania. Built in 1917, one bridge carried the Philadelphia & Reading Railroad (later the Reading Company) on its Philadelphia & Chester Branch, while the other served the Pennsylvania Railroad's Chester & Philadelphia Branch.
Today, one bridge remains in use by CSX Transportation and Norfolk Southern Railway. The other was abandoned in 1976 following the formation of Conrail.
