Interurban streetcars in Southern New England

Southern New England at one time had a large network of interurban streetcar lines. It was possible to go from New York City to Boston completely using these lines, with a choice of route (via Providence, Rhode Island or Springfield, Massachusetts). These routes matched the earlier split between Lower and Upper Boston Post Roads and the pre-1999 split of Amtrak's Acela Regional service (no longer through via Springfield).

Nowadays, the only services that come close to the definition of an interurban are the Green Line D (Riverside) branch and the Ashmont-Mattapan High Speed Line, both in the Boston area.
