The majority of signals between New York City and Washington DC are what used to be Position Light signals inherited from the Pennsylvania Railroad. Amtrak changed over the signals to what most call Position Color Light signals, in contrast to the Color Position Light signals that appeared on the B&O RR. They blanked out the middle, or pivot lamp on the upper head, for it was no longer needed, and on the bottom head, they changed the pivot lamp to white, which is only used for Stop and Proceed.
There are a few places where the PCL signals are not used.
One is the approach to Union Station in Washington DC where B&O CPL signals are used in two places. The first is a high signal behind a hotel along New York Ave, a unique signal, for it is a B&O CPL signal made out of PL signal parts and colored lenses. The second place are the three signal bridges over the station leads, where modified dwarf CPL's are used.
In Havre de Grace MD, Amtrak uses "tri-light" signals where the main line goes from 4 to 2 tracks, on both sides of the interlocking. The signals on the northbound side sit on a signal bridge. The SB signals are mast mounted. The signals are also outfitted with LED's.
In Wilmington DE, on the north side of the station, they have a couple of Pedestal signals mounted above the track on a signal bridge. Amtrak has installed LED's in some of the lamp positions.
