Orange Line Track and Signal Upgrades (2022)
As part of the Orange Line Transformation Program, we accelerated important reliability upgrades during a 30-day shutdown of the entire line from 9 PM on August 19 through September 18, during which crews completed multiple projects more than five years faster than originally planned.
Regular Orange Line service returns with the first train the morning of Monday, September 19.
Building a Better T
As part of our $9.6 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.
Why We're Doing This Work
Upgrades to Orange Line tracks and signals will improve safety, increase reliability, and provide smoother trips for riders.
- Replacing 6,300 feet of rail near Wellington station, plus other upgrades along the Orange Line
- Replacing two crossovers
- Installing new signaling systems at Oak Grove and Malden Center stations
- Repairing track along the Southwest Corridor
- Replacing rail ties between North and Wellington stations
- Safety: New tracks, ties, and ballast will reduce the risk of high-impact events such as derailments
- Reliability: Track and tie replacement will allow us to remove speed restrictions, resulting in faster travel times and fewer unplanned stops
