Red Line Transformation Program
As part of the Capital Transformation Program, the Red Line Transformation (RLT) is improving the quality of service for the T’s most popular line.
The RLT program will help increase service frequency, improve reliability, and enhance operations. This program will also support the expansion of Red Line fleet, which will increase train capacity and rider comfort. Achieving this requires major upgrades to train yards, maintenance facilities, testing facilities, signals, and power systems.
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.
