Seriously a no-brainer, because THE ENTIRE TRAIN ROUTE EXISTS ALREADY!!! This is an old basically unused shipping rail line that already runs through Brooklyn and Queens! So they don’t have to do the biggest hardest part of building a new rail line in a packed city - the tunneling! All they have to do is install stations for the train to stop at! That’s still a big project of course, but the hardest part is already pre-created!
