Joe Barker has it right That is the Bay Ridge Yard of the Long Island RR. The car floats are in the background The New Haven ran over the Hellgate Bridge & the NY Connecting through Fresh Pond and down the BayRidge branch of the LIRR to get to the NY Harbor car floats The Long Island switched this yard with BB-3 rats and later Alco S-2's The catenary came down in 1968 and the floats were abondoned the next year when the New HAven became part of Penn Central
