It's a nightmare getting home on commuter-rail trains out of South Station because of an Amtrak train that took out one of the overhead power lines near Back Bay. Or as the T puts it:
Framingham/Worcester, Needham, Franklin/Foxboro Line & Providence/Stoughton Line passengers are experiencing severe delays in both directions due to a downed catenary wire & earlier disabled Amtrak train. All trains must operate on one track at Back Bay.
