The Massachusetts Bay Transportation Authority has shut down service on a large stretch of the Green Line because of rising water on the Muddy River.
MBTA Spokesman Joe Pesaturo says crews are using sandbags to build a dam at a station near Fenway Park, where the river has risen to about 15 feet.
Train service has been suspended from Reservoir Station to Kenmore Square, and buses are being used to take passengers from station to station.
The flooding is being caused by the nor'easter that moved through the area this weekend, bringing heavy rain and wind gusts of nearly 60 mph.
Pesaturo did not know when service would be restored.
