The Metropolitan Transportation Authority (MTA) announced that crews have completed an extension of track east of Great Neck.

The extension will ensure greater service reliability on the Port Washington Branch with the projected service increase associated with the opening of Grand Central Madison, according to MTA's news release.

The segment of track underneath the recently replaced Colonial Road Bridge was extended 1,100 feet to enable the storage of an additional train of up to 12 cars, an upgrade from the existing track in the area that already accommodated one train of up to 12 cars.

MTA added this extension allows the Long Island Rail Road (LIRR) to store and turn more trains on the Port Washington Branch, and stage an additional train to operate extra service from Mets-Willets Pt.

“This infrastructure improvement enables the LIRR to run more trains more reliably on the Port Washington Branch,” said Catherine Rinaldi, MTA Long Island Rail Road interim president. “Completion of this work brings us one step closer to the launch of LIRR’s historic new service to Grand Central Madison, the largest service expansion in LIRR history.”

Under the draft schedules that include service to Grand Central Madison, Port Washington Branch customers will benefit from 36% more AM Peak service and 42% more PM Peak service. The number of local trains terminating or originating at Great Neck and making all local stops to or from Manhattan increases to 20 per weekday after the opening of Grand Central Madison, up from 11 today, an increase of 82%, according to the MTA.

Although the opening of Grand Central Madison was not contingent upon the completion of this project, MTA said it is part of the LIRR’s East Side Access Readiness Plan to enhance the reliability of service that is commensurate with the increase of trains. The project was comprised of three main segments: replacement of the previous century-old bridge that carries Colonial Road over the Port Washington Branch in Great Neck, improvement of drainage at track level, and the track extension.
