Crystal Lake, NY: BR&P+B&S Depot

(Satellite, my guess based on the topo map and satellite image below.)

BR&P = Buffalo, Rochester & Pittsburgh

B&S = Buffalo & Susquehanna

The Buffalo Rochester and Pittsburgh Railway Company posted
Crystal Lake station on the Rochester Division between Farmersville and Freedom. The station was built by the Buffalo and Susquehanna Railroad and shared with the BR&P. The station still stands, and is part of camp Scouthaven.

Note that the railroad went through Farmersville Station instead of Farmersville.

1942/42 Franklinville Quad @ 62,500

Note that they had a spur to serve the depot.
