I think that the train should go on Second Avenue with the . The Starting from Seneca Avenue, then going up onto Queens Blvd Line, onto Second Avenue, then Fulton, and terminating at Lefferts Blvd. This will free up the so it can go to Far Rockaway 24/7 and the can go to Rockaway Park. I don't really care were the goes as long as there is Manhattan and Bronx service.
