Queeensborough Plaza was the largest station in the Elevated system and as large as the West 4th street complex on the IND lines. Until 1949, service was provided jointly by the IRT and BMT divisions. Until 1942, the IRT second Avenue Elevated operated over the Queensboro Bridge and ran trains to both Astoria and Flushing . The IRT Steinway Line( What is now the number 7) provided service to both branches from Times Square. BMT El Trains served both branches with Trains originating at Queensboro Plaza as well as a Round Robin Operation between Ditmars Blvd and Main street Flushing. BMT subway trains used the 60th street tunnel to arrive at Queensboro plaza with passengers transferring to the BMT EL service for either Branch. The track work was a a great complex arrangement that permitted all these operations. Here are a few aerial views. The North side of the station was removed in the 1960's since it had not bee used since 1949.
This one is probably 1949-50 right after joint operations ended.
