MBTA continues Assembly Station Project progress

Written by Jenifer Nunez, assistant editor

Massachusetts Bay Transportation Authority's Assembly Station Project is well underway. The new Orange Line station is under construction between Wellington and Sullivan Square Stations. Once complete, the station will serve as a gateway to development at Assembly Square.

Between July 2012 and February 2013, the project has completed the subway track infrastructure that will allow train traffic to be shifted east. This shift creates space for Assembly Station’s future platforms. The work throughout these past few months has included rehabilitating the test track, reconfiguring the third rail and relocating the signal and communication systems. This work was performed directly on the Orange Line tracks and could not be completed while trains were running. Major portions of the track work were performed during scheduled weekend diversions between Oak Grove and Sullivan Square Stations.

In addition, the “early access nights,” in which Orange Line service was suspended between Oak Grove and Sullivan Square at night Sundays through Thursdays, provided a six-hour window that accelerated the schedule and allowed for the infrastructure work to be completed by December 2012.

Since January 2013, installation of the concrete piles has been performed during Orange Line weekend diversions. The concrete piles support the new southbound tracks and platform areas of the future Assembly Station.

The project will be complete approximately by Fall 2014.
