Great video!
Looking south (west) toward the signal bridge, track layout was (l to r) Track 2 eastbound (northbound), Track 1 westbound (southbound), siding 1 (?) and siding 2. The middle two tracks (westbound 1 and siding 1) switched off to the right to Manasquan, siding 2 merged into siding 1 at the turn. A crossover connected Track 1 to Track 2.
Wish I could draw it here.
There was no wye, just two tracks turning off to Manasquan, and two tracks proceeding toward Bay Head.
Looking west/south at the bridge, the CNJ-style signals were (l to r) one bottom target, three vertical targets, one bottom target, one bottom target.
There's a good track layout pic in Don Wood's "Unique New York & Long Branch" book, of the Doodlebug and an RPO entering the NY&LB at Sea Girt.
