Steinway Tunnel Trolley Map 1907 and Queensboro Plaza Area Maps

  The Queensboro Plaza elevated station has today four tracks on two levels with center island platforms.  In years past, the complex was more complex with eight tracks on two levels.  The service pattern was more complex with joint BMT IRT operation on I believe both branches. The 2nd Avenue El also ran to the plaza after crossing the Queensboro Bridge.  In the left hand corner of one of the maps, is an interesting diagram of the Steinway Tunnel Trolley that was originally built between Lexington Avenue (Grand Central) and 21Street in Queens.  I believe that although the wire was up and the system was complete, no revenue trips were run using trolleys and the tunnel was unused after many years until it was converted to subway rapid transit configuration with third rails.  These two tubes are used today by Number 7 Flushing Line trains.
