Greenbush should be easy

The Glob reports that the Silver Lie South Boston project is the MBTA's "first major expansion since the extension of the Red Line to Alewife in 1984". I guess the Southwest Corridor project (1987) doesn't count -- "it's not an extension, it's a relocation". Nor do the Newburyport or Old Colony commuter rail projects (both around 2000), which together I think add about 100 route-miles to the commuter rail system. The T should just do things like Greenbush and the Fall River/New Bedford projects; since commuter rail doesn't qualify as a "major expansion" those should be cheap and easy, right?
