In recent years I've heard about public interest in reactivating the express tracks along the Culver Line in Brooklyn for revenue service. I recently found out that those are far from the only unused express tracks within the entire subway system, so I've been wondering: [1] Why is there so much public interest in the Culver express tracks and little or no interest in other unused express tracks? [2] If the public succeeds in getting the Culver express tracks reactivated for revenue service, will other unused express tracks follow suit later on?
(BTW, my own personal opinion about Culver express service is as follows: If any existing runs are to be converted to express runs, they must be adequately replaced with additional local runs; otherwise, there will be many dissatisfied passengers at the local stations. A renovation of the Bergen Street express platforms may also be in order if express service were to be revived.)
