Posted by randyo on Fri Feb 16 16:40:34 2007, in response to Re: New switch-a-coming, posted by G1Ravage on Fri Feb 16 02:04:29 2007. That was back around 1949 when the BMT and IRT shared both the Flushing and Astoria Lines. The present BMT tracks at Qbro Plz were riginally lined up with the 2 Av El tracks over the Qbro Brge. The existing xover on the upper level was used to route the appropriate IRT trains to either Astoria or Flushing from the Steinway tubes or the 2 Av El. Actually, since the original platforms were shorter, the lower level diamond Xover was at what is now the south end of the S/B platform. The Xover had to be removed when the BMT was routed onto the former 2 Av El tracks and the platforms lengthened accordingly. Platform extensions, however did not interfere with the upper level Xover and that one was retained. The different grades for the approach to Qbro Plz lower prevented the lower level platform from being extended north or the moving of the diamond Xover to N/O the station. |
