That is correct. Back when the B was the West End service, there were actaully 4 Bs on the late PM that operated via the F Line to Bway/Laff where they went in service there. This was also before the 63 St connector opened up and the Bs terminated at 21 St during late PMs and weekends. There were also 2 Ns that operated over the Brighton Line to Dekalb for the same reason although I dont recall whether they ran light or in service, to provide "windows" for work trains operating on 4 Ave. Also, due to the work trains, there were some S/B Rs that turned at either Canal or Whithall St to provide N/B service into Queens and the headway N/B out of 95 st was opened and adjusted by holds at Whitehall and Canal St to blend with the short turns. The reason that the Rs were impacted was that some of these work trains had to operate vis the Montague St Tunnel to get to locations in the Eastern Division so windows were required there as well.
