Another electrification question...I recall a couple past posts from F-Line such as this one saying Stoughton can't be wired until a decision on pursuing South Coast Rail Phase 2 (the official, "Stoughton Electric" version) is made, because optimal substation siting will depend on whether the Stoughton Branch remains short or feeds into a much longer route.
But given how short the Stoughton Branch is, why couldn't it be chained off an expanded Sharon substation like the (twice as long) Fairmount Line would be, and thereby sidestep the SCR Phase 2 considerations? (In other words, if there's a way to wire up the branch without having to build even a mini substation, then why would there be any dependency on SCR Phase 2 planning?)
