This photo was taken by Max Hubacher in 1954 and was obtained from the source above.  I do not believe that this is the view from the Avenue "N" station because you will see some interesting items.  Incidentally, you are seeing a southbound BMT Culver Line train composed of BMT Standard cars,  I think the B Types with roof vents.  The "S & M Plumbing & Heating Supplies" I believe is right at the private right of way of the Bay Ridge Division LIRR.  At that time, this branch operated with overhead high voltage wires and you can see the silver painted high tension wire support to the left of the train.  I believe part of that support may exist today and you can see it while looking out the west side of a southbound "F" train.  I believe that behind the train you can see the double platform 18th Avenue station.  The high wire support raised the high tension wires above the level of the Culver Line.  Notice the small yard to the left.  I believe that I may have seen a map years ago showing this.  This site today is occupied by "Amazing Savings" and other big stores near the Avenue "I" station.  The building dealing with plumbing supplies I believe still exists and has been refurnished.  The only electric transportation in this area is only the present day "F" train.  The LIRR pulled the plug on overhead power at this location many decades ago and the wires for the South Brooklyn Railroad and McDonald Avenue Trolley were gone by 1965. The tracks under the el lingered for a few more decades but were removed within the last twenty years because they were said to be hazard to motorists.
The map below comes from a great South Brooklyn RR site and shows the Parkville interchange.
ca. 1920 - ca. 1959
