Penn Sta colorlights can display all three colors on the top unit and I think all three on the bottom. Total of... five aspects?
Dunno if they ever had third rail on tracks 1-4-- presumably they don't now. But it must be on tracks 5-21.
I wonder why if the MNRR diesels work with the 3rd rails why they dont just use them and save the diesel for north of Croton Harmon.
Here's a pic of the NYP signals (courtesy of Jersey_Mike) :

I assume the top left is a Green Light, the top right is a Yellow and below the two is a Red Light. Then below that there is the signal name board. Below the signal board is another Red which seems to light up in unison with the top one. Below that however I cannot make out what kind of bulb that is (maybe a yellow or a lunar white?).
My theory is that they operate like a single head dwarf with just the two reds for STOP.
However, if someone will eb able to identify the bottom bulb as a color then maybe they could operate like a double headed signal.

I am looking over Rich E. Greene's charts (this one in specific:
http://www.richegreen.com/MNRRv6.pdf) and I think what your saying makes sense.
The tracks 1 to 4 just stub out so yeah it would make sense not to have a third rail. I think some LD trains going South originate off those tracks though. The 5 track stubs out but it also curves back into the bowl. I wonder if its stub is electrified. Maybe that track is where the LSL originates/terminates.
I am also going to assume that the 1E through 6E tracks don't have third rail because they just stub out. I think that also hold true for the 1A-3A and 5A stub tracks.
The tracks that are controversial to me now are the 1C through 10C stubs. They are near the L.I.R.R. platforms so they might be 3rd rail electrified for those trains but I dunno about Catenary.
Some clarification here would be great.
Finally this photo by Jersey_Mike of the "diagonal platform I am going to assume is the old Mail Platform. Maybe, maybe not?
