- Identify any significant changes to the context within which the NSRL would be implemented, such as demographic shifts, new transportation technologies and trends, and changes to the built environment.
- Determine the major elements of the NSRL necessary to allow for an assessment of costs and benefits (two versus four tracks, whether or not to include a Central Station, the location of the north portal, as well as station and headhouse locations).
- Identify a Right of Way envelope that could be used to inform future development plans in Boston, Cambridge, and potentially other impacted municipalities.
- Develop an order of magnitude cost estimate, assuming the initial use of dual-mode locomotives allows the project to advance without full electrification of the commuter rail system. This cost estimate will be informed by recent experience in rail tunnel construction (both international and domestic) and industry best practices.
- Estimate the benefits of NSRL, including ridership growth, increased system capacity, operational efficiencies, air quality improvements, and the creation of new redevelopment opportunities.
