Sorry, I forgot about the new Newark Airport station.
I was refering to the Newark Penn Station..I'll use NWK
from now on.
Here is a great photo, from the nycsubway site...
It is taken from the old Journal Square platform, looking east.
The train is the original H&M "Black cars"
Notice that...all tracks have overhead wires, and PRR signals, and Waldo tower, which controlled the interlocking.
The 2 tracks to the far left are the freight tracks, which were in use till
the mid 1990's, or so.
The tracks ahead...the 2 inner are the PRR/H&M tracks to grove street and beyond. The 2 outer tracks went to Exchange place, the PRR's Jersey City terminal.
This is all pre-New York Penn Station trackage...you could take a Pennsy train to Journal Square, and change to the H&M train to get into Manhattan.
The last PRR train to use the outer tracks to Exchange Place was late 50's-early 60's...the NYLB diesel trains to Bay head I think were the last.
By 1964 the 2 outer tracks were derelict, and by 1970, PATH owned the ROW and rebuilt all 4 tracks with 3rd rail, no overhead wire, and color light signals. The Journal Square station was rebuilt at this time, too.
I remember all this from the early 60's, but this is the 1st pic I've seen.
