MBTA Board of Directors Awards Contract for Major Track and Signal Upgrades at South Station

Posted on March 23, 2023

Today the MBTA Board of Directors awarded a construction contract of over $98 million to upgrade the tracks, switches, and signals at South Station, which will result in improvements to the reliability and resiliency of Commuter Rail and Amtrak train service into and out of the station.

The project will provide better operational reliability to the MBTA’s nine Commuter Rail lines that terminate at South Station as well as Amtrak’s Northeast Corridor and Lake Shore Limited services while also improving safety, resiliency, and security. When complete, the project at South Station will address immediate state-of-good-repair needs of current train service while also supporting future growth of both the MBTA and Amtrak through numerous upgrades to track, signals, communications, and interlocking infrastructure. In addition to track and signal work, this project includes installation of a new master signal house, a new backup generator, inverter, and transformer system; switch heaters as well as electrical and signal cable trough systems; new LED lighting of the track and overhead wire areas; and provide new security systems, including cameras and fencing. 
The contract, which was awarded to Middlesex Corporation, will be funded through a combination of sources including $41.2 million of Federal Railroad Administration State of Good Repair Grant as well as additional funds from the MBTA and Amtrak. 
Under the project schedule, work is expected to begin in April and will reach substantial completion in late 2027 with final completion anticipated in spring 2028.
