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. |

What I don't get is why go back to 39th Ave when they can continue on wrong rail beyond QBP to the switch by the mouth of the 60th st tunnel & switch over to the Manhattan Bound track there? |

Posted by italianstallion on Sat Apr 13 16:48:58 2019, in response to Re: flushing line isolation, posted by AlM on Fri Apr 12 20:00:53 2019. Why is that so? Just build a transfer station somewhere where they can change to the subway line. |

At the time this was proposed (early 1970s?), there was much less reverse commuting.A 1969 employee's timetable shows 16 Harlem and 17 New Haven trains in the 5:00-6:00 hour. |

A transfer from the 7 line to the BMT from the north involves these steps. I should know I've done it myself...1. Train goes through QBP lower and continues 2. Train enters Hunters Point Ave station, change ends. 3. Goes over switch from Southbound to Northbound track 4. Heads back to QBP upper level. 5. Get bottom yellow switch from 7 line to N/W line routed to middle track as they call it Beebe Middle. Change ends. 6. Go south on BMT. |

I actually witnessed a transfer during my 1999 visit (or was it 1994?) . Strange as it was during the PM peak. There was a R-33WF single at both ends bracketing to pairs of R-36WF. It delayed slightly a northbound 7 which was waiting just before the curve (I had transferred from the N at QBP, and was waiting for the 7 to go to 103, then Q23 to my hotel (Holiday Crown Plaza by LGA, which is no more). |
