Posted by gbs on Fri Apr 12 23:06:15 2019, in response to Re: flushing line isolation, posted by randyo on Fri Apr 12 19:50:10 2019. Those switches aren't really new anymore, but they do allow for an easier move from the #7 line to the BMT tracks. Prior to their installation, a train from Flushing (or Corona) that needed to enter the upper level of QBP had to be on the express track from Woodside. ( This map from nycsubway.org shows the old configuration.) Now a #7 train can approach QBP from either the express or local track (which merge), then crossover and enter QBP upper (wrong-railing), change ends, and crossover to the BMT. But they don't then change ends and wrong-rail through QBP upper on the BMT. Instead they continue north, switching to the middle track before 39 Av, then change ends and proceed normally on the south-bound track. |
