Green Line Transformation 2019 Year in Review

Updated on January 3, 2020

As 2020 begins, we’re celebrating what the Green Line Transformation team accomplished in 2019, and looking ahead to what’s coming this year.

We know that diversions and construction can be inconvenient at times, and we appreciate your understanding as we work to provide the quality of service you want and deserve.

Here’s a closer look at some of the important milestones we reached in 2019 and what to expect in 2020.

Building a Better T

As part of our $8 billion, 5-year capital investment plan, we're renovating stations, modernizing fare collection systems, upgrading services for our buses, subways, and ferries, and improving the accessibility of the entire system.

Intersection Upgrades

Our acceleration of the 30 intersection upgrades was completed 5 months ahead of the original schedule by maximizing planned diversions. These upgrades bring you a safer, more reliable MBTA.

In addition to accelerating the intersection upgrades, the Green Line Transformation team took advantage of the planned service diversion and incorporated more than 7,000 feet of track replacement work during the intersection work to maximize outcomes for our riders. We ultimately exceeded our track work goal and replaced a total of 8,480 feet of track. D Branch Track and Signal Replacement

D Branch Track and Signal Replacement

A team of workers install new signal cables near Chestnut Hill on the Green Line D branch.

Since fall 2018, we have been replacing track and signals on the D Branch. This project will improve service, safety, and reliability with new track and updated signal systems. To date, we have replaced 10,200 feet of track and several miles of signal cable.

D Branch shuttles will continue to replace train service on some weeknights and some weekends in 2020 as we work to replace a total of 25,000 feet of track and 6.5 miles of signal cable, which will enable us to lift speed restrictions on the Green Line D Branch.

Fenway Portal Project

Crews work on the tracks near the Fenway Portal

The Fenway Portal Project will reduce the risk of flooding damage on the Green Line and mitigate weather-related service interruptions.

Site work has begun to prepare for the installation of large steel doors at the entrance of the Green Line tunnel, as well as a steel gate just outside the entrance of the Green Line tunnel, near Fenway Station to prevent flooding. Crews will also install an updated pumping station, and new cameras to monitor potential flooding of the Muddy River and rising water levels that could pose a flood risk to our system.

D Branch shuttles will continue to replace train service on some weeknights and some weekends in 2020.
