Fall River/New Bedford Commuter Rail (South Coast Rail)

[F-Line to Dudley]

Still, there are other places that badly need a second track - particularly just north of Middleborough, and north of East Taunton. (There is double track at East Taunton, but no crossover north of the station, so through trains can't pass while a shuttle train is at the station. There's also a chunk of slow trackage through the yard north of Middleborough.

Even the Buzzards Bay commuter rail feasibility study proposed siding lengthenings on the existing Middleboro branch because of the way meets changed with the longer running distance requiring more resilience on the track layout. Probably the Middleboro siding and the Randolph siding would've seen significant extension. Still would've left the north-of-Braintree mainline a little brittle, but would've allowed the branch itself to sponge up most of the uncertainty factor and beat back any cascading delays.

That they never considered this for SCR when the fudge factor considerations were worse than Buzzards Bay because of the extra branching is a scandal.
