Summary
Former 66L w:position light signals at CORK interlocking in w:Lancaster, PA on w:Amtrak's w:Philadelphia to Harrisburg Main Line. These signals were removed in 2008 as part of a re-signaling scheme. The transformer visible is a 91.6 Hz, 6.9 kV step-down transformer that supplies power to track detection circuits, which must operate at a different frequency from traction power to avoid interference.
