The MBTA fiscal control board is considering a scaled-back proposal to extend the Green Line.

Consultants hired by the T outlined a new, simpler version of the project. The Green Line would still go to Medford, but instead of full stations, each of the six new stops would have a weather shelter. Instead of the 10,000-foot bike and pedestrian path, it would be cut down to 7,000 feet, and a more simple design.

The board could make a decision Monday, or in the weeks ahead, to accept a simpler version, or scrap it altogether. While a decision is pending, it got us thinking about how the Big Dig — moving Interstate 93 underground in downtown Boston — translated into a legal agreement to extend light rail to Somerville and Medford.
