Boston is shutting down all subways and trains on Monday night

The Massachusetts Bay Transportation Authority has announced that all rail service in and out of Boston will shut down Monday night at 7:00 p.m. ET.

According to the MBTA, difficulty keeping the the rails in safe working order during the snow storm means that no subways, trolleys, or commuter trains will depart from Boston after that time.

However, limited bus service will continue to run until the end of normal operational hours, with no rail transfers available.

Boston has been walloped by a third snow storm in as many weeks. Forecasters predict the area will be hit by as much as 18-24 inches of snow by Tuesday.
