The MBTA announced Wednesday that it plans to reopen by Monday most of the remaining segments of the public transit system that have been shut down due to the recent crippling snow storms.
The agency said that the E branch of the Green Line would reopen Friday, and the B branch would reopen Monday. The Red Line from JFK/UMass to North Quincy would reopen Friday, and service from North Quincy to Braintree would be restored on Monday, the agency said.
The Mattapan high-speed trolley line would be reopened by Friday, Feb. 27, the agency said in a a statement.
Shuttle buses had replaced the trolleys and trains as the public transit system struggled to restore service.
The statement said officials were "working hard to get train counts up," but, at the same time, emphasized that "reduced train counts due to the unprecedented winter storms will result in longer wait times and some crowding in the short term."
"Day after day with the help of the Governor's office, the National Guard and several partnering groups, our hardworking MBTA staff are recovering more stations and restoring service to more parts of the system," said MBTA General Manager, Dr. Beverly Scott.
Scott said the agency was "systematically executing a plan to recover remaining sections of the Orange, Green and Red lines while also working to get our maintenance facilities fully operational."
She warned that the goals would hinge on factors that included the weather. So far this winter, 96.3 inches of snow have been recorded in Boston, the second largest amount ever recorded here.
The agency said the Orange Line was at 56 percent of full service, the Red Line was at 79 percent, the Green Line was at 81 percent, and the Blue Line was at 92 percent.
Scott had said Monday it would take as long as 30 days to get the system back to normal.
Meanwhile, public transit commuters continued to experience delays Wednesday and the T urged people to repeatedly check for service updates at mbta.com.
In addition to experiencing problems with its trolleys, subway trains, ferries, and buses, the T has been having problems with the commuter rail system.
Governor Charlie Baker met with officials of Keolis, the company that runs commuter rail for the T, Wednesday morning at the State House. He said afterwards he had demanded better service and told the officials to be prepared for increased demand on Monday, when February school vacation week ends.
