Bus service will be available on an extremely limited basis, with various buses on snow routes, but the buses will run with delays due to traffic congestion and local street conditions, Pesaturo said.

The move was made so maintenance crews can continue to clear snow and ice from tracks, the third rail, and switches, Pesaturo said in a statement.

All MBTA rail services were suspended at 7 p.m. Monday, and will continue to be suspended through Tuesday, according to MBTA spokesman Joe Pesaturo. This means that no subway, trolleys, or commuter rail trains will be available until Wednesday.

The move also means that bus customers will not be able to make transfers to rail services, Pesaturo said.


Before announcing that all rail service would be suspended, the MBTA Commuter Rail had announced that it was halting all inbound service to Boston, but that outbound service would continue.

The MBTA’s subway lines operated on a reduced schedule all of Monday, with portions of major subway lines being replaced by bus service. The long-duration storm forced the MBTA to shut down the Braintree branch of the Red Line — where a train became stranded between stations for about two hours in Quincy — for the rest of Monday.

It also earlier announced it was halting Orange Line service between Oak Grove and the Sullivan Square station for the rest of Monday.

Speaking Monday afternoon, Governor Charlie Baker declared a snow emergency and also declared a partial state snow day Tuesday for non-emergency personnel who live or work in Suffolk, Norfolk, Essex, and Middlesex counties.

Speaking earlier in the day, Baker called the MBTA’s response to Monday’s snowstorm “not acceptable’’ after the mass transit agency said its operations for the evening commute will fall below the already reduced level of service it provided for the morning commute.


“The only other thing I want to mention is that we’ve been frustrated, disappointed with the performance of the T,’’ the governor said at an afternoon press conference in Dorchester. “The public transportation system has to work. Let’s face it, this can’t happen again.”

Baker was more measured in the evening news conference, saying he did not want to get into a “blame game” and that he wanted to be debriefed on the T’s decisions “once the dust settles.”

Speaking separately, Boston Mayor Martin J. Walsh said City Hall will be closed for the second straight day on Tuesday and asked private employers to let workers stay home on Tuesday so the city can turn its attention to snow removal.

“We are going to get all of your streets,’’ Walsh also promised residents. “We will get to every street in the city of Boston. We will get to every neighborhood in the city of Boston.’’

The storm marks the third consecutive time in as many weeks that Massachusetts has been battered by snow. More than 20 inches have accumulated in Boston since Saturday, and the National Weather Service forecast predicts up to 36 inches could fall by the time the storm is done early Tuesday morning.

The weather service said 76.5 inches have fallen in Boston this winter season, including 71.8 inches in the past 30 days.
