Unfortunately, even though it gets heartbreakingly close to both Broadway and SS the dang thing just isn't aligned in a useful way to support an revenue destination. Which sucks because the old upper-level Broadway trolley tunnel has an existing portal that stares right out across the street into Cabot...but the loop arrangement inside is weird for rapid-transit dimensions and thus couldn't possibly be used even if you did reclaim the upper level lobby and did do the quick duck-unders tunneling from the Cabot ROW under Dot Ave. and back underneath Foundry St. And likewise there is just too much cross-trackage, the Ft. Pt. Channel, and a few big-ass buildings in the way to get on-alignment the last 1500 feet from the yard to SS. And, really, there were previous obstructions there too even historically--through several iterations of buildings and train yard configurations on the site--that there was never a realistic possibility of doing that. Not without greater coordination across various private property interests than was probably possible at the time.FP10 wrote:Could someone explain why the red line would even need the south station loop, if it hypothetically did align and all that.Downtown Boston doesn't have a large rapid transit terminal whereby crowds and trains can be staged to accomodate large crowds resulting from special events in an operating situation where the staging of multiple stationary trains won't impede headway along the line.
