>>1951496>double the Green Line tracks in Downtown or at least build an interchange station at BoylstonNo space available, there is space at Boylston although the former portal is built over and its a park now
>run one or two Green Line branches to the Airport proper and replace the Silver Line meme bus, possibly connect that part of the Green Line to the Blue LineNo space available and it conflicts with one of the most important highway intersections in the entire city
>Extend the Blue Line south to either Nubian or along the Green D to Riverside (if the latter, let a Green Line branch go to Nubian, should be feasible with the aformentioned doubling of tracks)Blue line to riverside is an option that people have talked about in the past but its most likely being sidelined until they do more productive shit with the blue line like extending it to charles/mgh and lynn
>Extend the Red Line proper to Mattapan, 99% of people prefer direct services over heritage rolling stock. Also relocate the Mattapan terminal to the Blue Hill Avenue railroad station.No space to relocate the terminal, not enough ridership to justify making it light rail, also the people using the line prefer the dinky little streetcars because its charming and it keeps real estate prices high
>Extend the Red Line north to ArlingtonNot happening for a while and if they do it'll probably get extended out to Lexington aswell
>Build a Green Line branch to Watertown via Boston Landing, maybe even extend it to the Fitchburg LineThere's already a route for this along the historic A line, also probably not happening for a while until more productive shit happens
>build a commuter rail line connecting South and North Stations, a similar project to London's Crossrail/Elizabeth LineThis is a really tricky one because people want it to happen but it would require rebuilding North and South stations since theyre both not built to carry through traffic (as well as a massive tunnel thru boston)
