Three (3) wyes attached:

 

1.  Wye at Upton Junction

2.  Wye at Manorville

3.  “Wye” at Eastport.  

 

While #3 appears just to be a switch with curving track, it was referred to by the railroad AS a wye.  Emery refers to it as the “west leg of wye” on his map.  This allowed eastbound trains on the Manorville-Eastport branch to change direction without a reverse move.  This was done for the smooth handling of troop trains.  One-way routing:  eastbound over the Main Line into the camp and westbound out of the camp via the east leg of the Upton Jct. wye to the Main Line then via Manorville-Eastport branch to the wye at Eastport and, changing direction, westbound along the Montauk branch.

 

Enjoy!
