I can hardly blame them for deferring freight, considering the already strained capacity, and the relative inability to make any significant changes to capacity by infrastructure changes; and the economic importance of keeping passengers flowing is such a priority for the region. At the same time, though, the lack of a convenient east-west route until you get to the B&A mainline is an equally huge problem as jeopardizing passenger capacity, since the highway routes that become the alternative are overcapacity too. Don't really know what a solution to this would be, though. The next closest thing to creating an east-west line is going to be whenever Amtrak actually gets to building their inland route, but that starts skewing away from the New Haven Line and Shore Line pretty fast (since the point of it is to avoid it). But that's at least two decades away, and anyone's guess is as good as mine at how hostile Amtrak would decide to be against freight there.
Anyways, based on the P&W railfan timetable from Oxford Junction Press (effective date of Jan. 2012), I can see the following freight spurs noted on the New Haven Line between New Rochelle and New Haven:
Mamaroneck "Yard" in Mamroneck, NY at MP 19.70, servicing Marval Industries; Pepperidge Farms Spur in Westport, CT at MP 43.70, this is definitely gone at this point (used to stop near/go over Route 136); Stratford Industrial Track in Stratford (not listed, but still extant as noted earlier in thread); the #5 freight track starts at MP 64.80 in Milford, CT; Waste Conversion has a siding at MP 65.10, Furmann Lumber at MP 65.70, and Jefferson-Smurfit at MP 66.77, all in Milford and off of the #5 track; and finally all of the following in West Haven: Star Distribution at MP 68.20 off of track #5, Miller Supply at MP 68.30 off of track #4 (southernmost track), Eder Brothers at MP 68.40 off of track #5, and A.J. Schaffel at MP 69.60 off of track #5
I used the P&W one instead of CSX, even if they just have overhead rights, because (in theory) it is about a decade newer in effective date. Please note that these could be inactive, but it gives a good idea what is
extant, or was recently extant.
And on an unrelated note, what would you even call the head type of that kind of signal... a traffic signal? Every now and again when they come up, I always have a hard time talking about them simply because I don't know what to
call them. I.E.: for the triangularly arranged position light heads up and down NORAC territory, the unofficial term "tri-light" gets used. Offhand the only other place I can think of with something like this is in Groton where
P&W's Old Groton Running track crosses Route 349; only services Electric Boat a couple times a year at most, so I figure it's a similar case to the one mentioned above.
