Mattapan Line Transformation

Trolley on Mattapan Line

We’re making improvements on the Mattapan Line to ensure accessible, reliable, and modern service for Dorchester, Mattapan, and Milton for years to come. 

The Mattapan Line serves 6,600 riders every day, and the historic 1940s trolley fleet runs on 2.6 miles of track between Ashmont, on the Red Line, and Mattapan Station. The route has eight stations and connects riders to many local bus routes and the Neponset River Trail.

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

At public meetings in Dorchester, Mattapan, and Milton, residents talked to us about the issues that are important to them, including accessibility, safety, and the historical significance of the existing Presidents’ Conference Committee (PCC) trolleys. 

Future improvements to the Mattapan Line will incorporate and reflect that feedback, and allow for the continuation of accessible, reliable, and safe service.

In the next eight to 10 years, we will make improvements to the existing fleet and infrastructure. We are also considering substantial changes that we might make beyond the next decade, including options for a new fleet and the infrastructure needed to support it.

Take the Survey

We want to hear from you about how you use the Mattapan Line and any improvements you want to see. The survey will be open through the end of winter 2023.
