The writer has just located an official large NYCTA engineeering drawing, #7-A-417-SLB, which may clarify some of the facts regarding the 76th Street Station. The original drawing was dated September 11, 1951, and titled: Block Signalling and Interlocking, General Signal Arrangement, Line "A", Pitkin Avenue Yard, Scale 1" = 80'. The drawing was updated on June 8, 1956 (just prior to the opening of the extension to the Rockaways). It shows the entire Pitkin yard and its connections to the mainline, Hudson Street ramp, and future 76th Street Interlocking. The drawing states "Traffic Control between Euclid Avenue and Future 76th Street Interlockings and Pitkin Avenue Yard Interlocking for Tracks A5, A6, A7 and A8." The drawing clearly shows active tracks, numbered A7 and A8, between the Pitkin Yard and the stub end bulkhead located approximately 270' northeast of switches numbered 65 and 67; these tracks had led to the 76th Street Station before the bulkhead installation. The bulkhead has the notation beside it stating "To 76th Street Line "A".
The map detailing where tracks A7 and A8 led to will be found on Drawing Number 7-A-370SL, which I do not have.
It will be quite interesting if the actual present day status of this never used section and station could be actually determined. It also appears strange that perhaps little or no routine infrastructure maintenance has been done to these abandoned tunnels or station since the bulkheads were erected, as has been routinely done with other unused NYCTA tunnels. If so, could this possibly, over a period of time, endanger the area directly above the tunnels?
One last thought, maybe a bit far out, but perhaps not. If this station and the surrounding areas do in fact still exist, would this not make an excellent satellite display area for the NYC Transit Museum, and provide good underground storage for the ever-growing fleet of museum cars?
