MTA Metro-North New Haven Line Mamaroneck Substation Replacement

The Village of Mamaroneck is sharing the following message on behalf of the MTA Construction and Development agency.

MTA Construction and Development on behalf of Metro-North Railroad is undertaking an important construction project in the vicinity of Rockland Avenue, Waverly Avenue, and Railroad Way along the Metro-North Railroad right of way. This project intends to keep Metro-North's infrastructure in a state of good repair, and to improve safety, resiliency, and reliability of trains operating on the New Haven Line. This project will replace the current obsolete outdoor substation in Mamaroneck with a new indoor enclosed substation next to the existing substation. This project will improve the power supply capacity and resiliency of the power supply of the New Haven Line. The overall project is expected to be completed by December 2026.

The Mamaroneck substation is located by catenary 128, adjacent to the commercial area near the Toyota City Service and Parts Center at 700 Waverly Ave. During the course of the entire project this work will cause loud noises due to construction work, including but not limited to movement of heavy equipment and machinery, large trucks, and train horns as they move through the community.

To facilitate this work, rubber track pads will be installed southwest of Rockland Avenue. The installation of these pads will take place between March 25th and April 15th. During this time, two or three nights of work will be required, with the exact dates determined by the MTA's ability to support the track outages needed to perform the work.
