him, rather than South Station, as the Massachusetts House of Representatives had voted unanimously to do. In August 2015, former Governors Dukakis and William F. Weld co-wrote an op-ed calling the link "One of the most important and cost-effective investments we can make". Based on their advocacy, MassDOT agreed to fund a $2 million study in February 2016. In June 2018, MassDOT released a North South Rail Link Feasibility Reassessment presentation that proposed several tunnel alternatives, described above. The state began soliciting bids for the $2 million feasibility study, advocated for by the North-South Rail Link Working Group, in March 2017. The study did not identify a funding source for constructing the NSRL. On September 6, 2018, MassDOT released their draft feasibility reassessment report and asked for public comment by October 19. In late 2022, with the election of Maura Healey as governor of Massachusetts, advocates of the North-South Rail Link began pushing for support for the project. Alternatives , the MBTA and Amtrak use the Grand Junction Line for non-revenue vehicle moves between the two sides of their networks. This alternative connection splits from the Framingham/Worcester Line near Boston University and the Mass Turnpike Allston/Brighton exit ramps, and the track then crosses the Charles River into Cambridge. From there, it runs through the East Cambridge neighborhood and into Somerville, where it connects to the commuter rail lines running from North Station, just below the McGrath-O'Brien Highway. The line is currently single-tracked east of Massachusetts Avenue and slow, with a large number of at-grade crossings. Several of the crossings (e.g. Massachusetts Avenue, several streets around Kendall Square, Cambridge Street, and Gore Street) require trains to come to a near-complete stop before proceeding at their maximum allowed track speed of . The line would potentially be served by a new West Station which is proposed as part of the Beacon Park Yard redevelopment. The Grand Junction corridor has also been proposed as part of the Urban Ring light rail or bus rapid transit project, or a possible pedestrian trail. However, only Worcester Line trains would be directly served, while all other trains from South Station lines would have to detour and reverse all the way to the west of Back Bay and Lansdowne stations to reach the Grand Junction connection. An above-ground rail link between South and North Stations was once proposed by the Boston-based Association for Public Transportation (which also
