McMahon completed a feasibility study of extending commuter rail service from Boston west of its current terminus in Fitchburg. Our firm led a multi-disciplinary team to determine the cost, benefits, schedule, and funding options for extending service. The feasibility study required evaluation of a multimodal set of service alternatives in order to satisfy FTA funding requirements. McMahon also led the public and stakeholder processes to determine locations for stations, and an associated 400 space parking facility. A 4.5 mile extension of commuter rail service to Wachusett Station and a passenger rail layover facility were identified as the preferred option, with a westward extension to Gardner preserved as a future option. McMahon prepared the NEPA compliant Environmental Assessment and the successful application for federal TIGER Discretionary grant funds, through the American Recovery and Reinvestment Act (ARRA) that allowed the project to be constructed.
