Back in the 1977-80 period, Joseph F> Eid produced three self-published books covering all the trolley lines in this area. Specifically, these were:
"Trolleys to the Fountain" (Monmouth County Electric) - 1980
"Trolleys in the Coast Cities" (Coast Cities Ry.) - 1979
"Trolleys Across the Sand Dunes" (Point Pleasant Traction, etc.) - 1977
These are long out of print, and I suppose that Eid is also out of print by now, but the address shown on his books is: 589 Carroll Fox Rd., Brick, NJ. You could try him, and if you strike out, try a used railroad book dealer like Ron's Books. Goood luck.
