Red Line Program
The Red Line Program is improving the quality of service for the T’s most popular line.
This 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.
