The Ft. Hamilton Parkway on the BMT Culver Line was never built in the Parkway Style

Not to long ago,  a reader of SUBCHAT asked why the Ft. Hamilton Parkway station, at 37th Street was built in the traditional BMT Dual Contracts style and not with a concrete arch, found at other parkway stations, throughout the city, such as Bay Parkway, Ocean Parkway, Pelham Parkway and other stations.  I cannot answer you but I will say that the former station at 37th Street and Ft. Hamilton Parkway is similar to the present day "Avenue P" station on the F train.  There is a booking hall under the station over Avenue P and parts of the platform area, are not covered with a canopy.  The former Ft. Hamilton Parkway also had one central entrance area. The picture below comes from a Culver Shuttle web site and shows the wooden wind screens that were never replaced with metal.  Notice the former walkway which was similar to the one at Avenue P and McDonald Avenues.

Perhaps a more elaborate  structure was not constructed because at the time of building (1914-19?), Ft. Hamilton Parkway was formerly called "Ft. Hamilton Avenue?".  Also, the area under the el was not paved, which was the former PRW of the Culver Line that ran on the surface. Of course, the street crossing was paved.  The area was a shabby area with a lot of South Brooklyn RR turnouts and perhaps it was not the place to make a fancy elevated structure, at least over the parkway.  It is ironic that if the second IND system would have been built, a branch off would have run under Ft. Hamilton Parkway to Bay Ridge, Bensonhurst and Staten Island.  Perhaps there would have been an interchange station between IND Staten Island trains and BMT Culver shuttle trains at this point and perhaps the structure would have been upgraded.  Just some thoughts though.  It is possible that under the el structure, up to Ft. Hamilton Parkway, parts of the South Brooklyn RR PRW may have had Third Rail .
