The Central Corridor Rail Line is a proposed passenger service route between New London, Connecticut, and Brattleboro, Vermont.

A primary purpose of the proposed service was to provide a rail link between state flagship schools UConn, UMass Amherst, and UVM.

Preparing the line for passenger service would require refurbishing the New England Central Railroad tracks, which also carry freight to New London's deepwater port.

New England Central estimates that similar upgrades (which include upgrading the track to standard 286,000 pound car loads) from the Massachusetts / Vermont border to New London would cost $18 million, while the full project including stations and rolling stock would cost $150 million.

In October 2012, an excursion train was run to raise support for the project, which has been endorsed by a number of the town governments along the line.

[5] In November 2012, officials from Mansfield, New London, Norwich, and Windham (all of which will be served by station stops) plus the Southeastern Connecticut Council of Governments signed an agreement to pursue funding for the service.

[11] In 2010 a proposal was put forward to use refurbished Budd Rail Diesel Cars,[12] which are less expensive to operate than conventional locomotive-and-carriage trains on lower-density routes like the Central Corridor.
