No decision on when Boston-area rail service will be restored; governor has criticized agency

The head of the Boston-area public transportation system says no decision has been made on when rail service will be restored.

The Massachusetts Bay Transportation Authority was largely shut down Tuesday even though the worst of the snowstorm that staggered parts of the Boston area was over.

MBTA General Manager Dr. Beverly Scott says she made the decision to shutter rail service on the nation's oldest transit system because of the buildup of snow and ice on the tracks and concerns for passengers' safety.

Scott says that she understands the inconvenience caused by the shutdown but that the aging system needs significant new investment to operate reliably.

Scott says she hasn't yet spoken with Gov. Charlie Baker, who on Monday called the T's performance "unacceptable."
