This oblique aerial photograph of the George Westinghouse Bridge fully demonstrates the rugged topography and the maze of railroad tracks. The view is looking northerly. From left to right is seen the through truss bridge of the Union Railroad. Underneath it is the PRR mainline, in blue, at milepost 341.3. The Port Perry Branch, in orange, is in the foreground passing beneath the largest arch of the Westinghouse Bridge. The manufacturing facility in the top right corner is the former Westinghouse Electric Company manufacturing facility. The Edgar Thomson steel mill is out of the view to the left
The combined 3 to 6 degree curve of the mainline beneath the bridge is evident.
