I think the B extension needs replies…
For CoolBoss: “Yes! Between the B’s first train from Brighton and 9 AM, and between 3:30 PM and 9 PM, the D would run Concourse Exp, terminating at Bedford, most likely due to capacity issues at Norwood. If anyone lives on Concourse and works in Midtown or around Times Square or further, you can just woosh to work on the D. Most likely during PM extensions, some yard trains will be running Not-in-Service until 145th Street where they will run as Ds or get more trains from Coney Island yard”
For Prior Post (his most recent comment): “If only Concourse had 4 tracks, then the D could run express full time. The IND is filled with changes that happened randomly, such as the Crosstown line through Franklin Avenue, which was shelved at 11:00 AM (oddly specific time)“
