Capital Transformation
Capital Transformation’s mission is to transform the T by investing in large, long-term system improvements to better the quality of service for MBTA rapid transit riders and neighboring communities.
Improvements include the current transformation programs for the Green, Orange, and Red lines, along with future programs such as Mattapan Transformation.
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.
2022 Year in Review
As 2022 comes to an end, we’re looking back at the accomplishments the Green Line, Orange Line, and Red Line Transformation teams achieved this year.
How We're Improving Service
The programs’ capital investments address different levels of transformation, which include:
- Improving safety
- Bringing infrastructure into a State of Good Repair
- Enhancing accessibility
- Replacing legacy fleets
- Increasing passenger capacity
- Modernizing rider experience
- Expanding service
Each level of transformation aims to improve reliability and overall quality for all riders and communities connected to the T.
Prioritizing Transparency and Communication
In addition to improving service, we strive to provide clear and helpful communication with the public throughout each project. We foster collaboration among internal departments to minimize service disruptions for riders. This includes:
- Accelerating work whenever possible
- Increasing accountability through transparent reporting on progress and outcomes
Green Line Transformation Program
The Green Line Transformation (GLT) is revitalizing the oldest transit line in the United States. This multibillion-dollar program includes new accessible stations, higher capacity vehicles, upgraded maintenance facilities and yards, new tracks and signals, and advanced technology like vehicle collision avoidance.
The portfolio of GLT projects will help improve safety, enhance accessibility, increase capacity, and modernize the rider experience on the Green Line. The GLT team is working closely with the communities of Boston, Brookline, Newton, Somerville, and Cambridge to address impacts on them and meet their needs.

Orange Line Transformation Program
The Orange Line Transformation (OLT) is upgrading the 120-year-old rapid transit line serving the communities of Malden, Medford, Somerville, and Boston.
These projects will result in more reliable trips, and less crowding on platforms and in stations. The OLT program will also support the expanding Orange Line fleet, increasing train capacity and rider comfort. Achieving this requires major upgrades to train yards, maintenance facilities, signals, and power systems.
