About the Project

Timeline: 2015 – 2022

We’re upgrading the signal system on the Red and Orange lines. The new, digital signal infrastructure will support new Red Line and Orange Line vehicles being brought into service and allow for more reliable service. 

Work is being done alongside infrastructure and maintenance equipment upgrades at Cabot Yard and Wellington Yard as part of the Red Line and Orange Line improvement programs.
