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.

Recent shutdowns eliminated the last of the Orange Line's speed restrictions, according to MBTA General Manager Phil Eng.

“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.

A 13-day suspension of service for maintenance on a portion of the Orange Line led to the lifting of 20 speed restrictions, the Massachusetts Bay Transportation Authority has announced. The ongoing, year-long Track Improvement Program has now reduced the amount of the MBTA rail transit system under speed restrictions to 1.
