The Massachusetts Bay Transportation Authority (MBTA) has completed critical track work on the Orange Line, lifting nine speed restrictions.

The MBTA’s Orange Line, which runs from Jamaica Plain in Boston to Malden, is free of slow zones for the first time in more than a decade, the transit agency announced Monday. The announcement from the T comes after stretches of the line were shuttered ...

A service suspension last month allowed for unencumbered access to track areas, and crews were able to lift nine speed restrictions.

“That will be the first time the Orange Line is restriction free in 15 years,” MBTA General Manager Phil Eng said during an appearance at the Greater Boston Chamber of Commerce on Wednesday.

Twenty speed restrictions on the MBTA's Orange Line were removed after successful completion of critical track work, officials said Wednesday. This month's service suspension from Forest Hills to North Station allowed crews to get tracks into a state of good repair, the MBTA said.
