The longest route on the NYC subway is precisely when you have an appointment and the train decides to stop because there's electrical issues, someone jumped on the track, "there's a train stopped ahead of us", the express decides to go local instead, someone is holding the door, your route involves the F/G or any line that serves less affluent neighborhoods...
