So there’s a shuttle bus that runs sometimes and will run for the duration of the 181st St elevator shutdown that is usually covered by a MCH bus, but then is supplemented by one or two MV buses. So how does the runs work with the buses—does the drivers cycle out and in from the M4 runs (particularly for the runs on the MCH bus), and do buses that run on the M4/98 make a run after their M4/98 run on the elevator shuttle?
