For the first time in 115 years, overnight subway service in New York City has been shut down to clean trains amid the pandemic

New York City’s subway system — the nation’s largest — went silent in the early morning hours Wednesday as the normally round-the-clock system shut down for train disinfecting.

Service was curtailed in late March, but is now being stopped entirely from 1 a.m. to 5 a.m. each day.

It’s the first time in 115 years service hasn’t been 24/7 except in times of emergency, and Governor Andrew Cuomo says there’s no way to know when service will return to normal, notes CBS New York.
