Build a commuter rail station on or near campus
There have been on and off proposals to utilize the Grand Junction Railroad tracks that run through the MIT campus for commuter rail service from North Station to the western suburbs. This might be done in conjunction with a proposed West Station to be built on the former Beacon Park Yard site in Alston that Harvard plans to develop. MIT could encourage these plans by offering to build a rail station on or near its campus to serve the Kendal Square area and perhaps the Massachusetts Avenue Corridor as well.
For starters, siting and designing several alternatives for such a station and analyzing their environmental impacts would make excellent projects for Architecture and Urban Planning students. As one of the largest employers in the area, MIT has an obligation to reduce the carbon footprint associated with the commuting it generates.
