New York City's subway system went silent in the early morning hours, as part of a plan for the normally round-the-clock system to shut down for train cleaning, according to AP.

The trains, which had been running on a reduced schedule since late March, are now going to be stopped from 1am to 5am each day.

Fewer trains had been running in the overnight hours anyway, but the shutdown allows for daily cleanings and for city workers to move homeless people who have been more visible in subway cars during the coronavirus.
