The MBTA today announced the successful completion of critical track work on the Orange Line while service was suspended between Oak Grove and Ruggles October 26 – 27 and between Oak Grove and North Station October 28 – November 1. As a result of unencumbered access to track areas, crews accomplished important work to lift nine speed restrictions, resulting in a safer, more reliable trip for riders.

Following additional Track Improvement Program work that took place on the line earlier last month, the Orange Line is now completely free of all speed restrictions for the first time since 2010. Currently, slow zones are affecting less than 1% of the entire subway system. The last slow zones are expected to be removed by the end of next month.

During these seven days of unencumbered access to this area of the Orange Line, work crews replaced nearly 17,500 feet of rail and 2,600 ties. During the 30-day Orange Line shutdown in 2022, crews replaced only 6,000 feet of rail and about 2,900 ties. The tremendous amount of work accomplished on the Orange Line this past month is due to the close collaboration and coordination of multiple work crews on-site and during the pre-planning phases of these service suspensions.

“I would like to thank the MBTA team members who have been part of the Track Improvement Program for their hard work and express appreciation to our riders for being flexible during construction,” said Transportation Secretary and CEO Monica Tibbits-Nutt. “Mobility access for everyone is critical and the successful completion of Orange Line projects advances our commitment to leave the communities where we live and work in better condition than we found them. Transportation systems have to work if we want our communities to thrive.”

“We made a commitment to the public to deliver safe, reliable trips and upon completion of this most recent work, I’m pleased to confirm another major step forward towards that promise – the Orange Line is now completely free of speed restrictions for the first time in 15 years,” said MBTA General Manager and CEO Phillip Eng. “Less than 1% of our subway system is now affected by track-related slow zones, down from March 2023 when we had the entire system running at restricted speeds. I’m confident we’re on schedule to eliminate all remaining restrictions by the end of this year. This is truly an all-hands-on-deck, cross-functional effort that exemplifies teamwork and determination. Moving beyond this, we are committed to addressing future needs timely and not allowing such conditions to build up, impacting all that depended on us. All the credit goes to my leadership team and our workforce for delivering essential repairs more efficiently and effectively. I’d be remiss if I didn’t thank our riders for their patience as we bring them the faster, safer, more reliable, and frequent trips that they deserve.”
