This just in from MassDOT:
Amtrak officials notified MassDOT today that the Amtrak signal failure will not be resolved by the start of the evening commute. Because of this Amtrak failure, the only commuter rail trains that will depart from South Station are those that serve the Providence/Attleboro and Stoughton Lines.
MassDOT is urging all other Commuter Rail passengers not to arrive at South Station. Instead, MBTA will post new schedules by 3:30 PM today indicating which trains will depart from the alternative stations. These alternative stations will include JFK/UMASS, Back Bay, Forest Hills, Quincy Center, and Braintree.
The new schedules for todayâ€™s commute will be posted on MBTA.com by 3:30 PM today.
