Re: Green Line eRconfiguration
The freights kick in maint money here, and everybody has their ass covered with insurance for freak accidents like the North Billerica platform edge collapse. Those STB filings I referred to about the Conn River Line sale to MassDOT are instructive; they sketch out exactly who pays for what on whose equipment puts wear-and-tear on the infrastructure. It's pretty cut-and-dried, no wiggle room for finger-pointing.
BTW...there's not frequent derailments because of this setup. The one-car mini-highs are designed to take that pounding and be semi-disposable. And the 1-car length where the platform is interfacing with the sway of only 1 freight car at a time is what mitigates the derailment risk. It's when you get a >1 car length platform that the lateral harmonics of the whole consist's sway induce a much higher strike rate and safety risk. Which is why they don't go >1 car with the mini-highs. (Perspective: you're still talking "shit happens" contingencies impossible to zero out even in a perfect world.)
Gauntlets: those do by their very nature have an inherently higher derailment risk because of the switches and rail-within-rail so close to a platform. First-worlder installations included, because they use those in Europe too to get freight around their high platforms. This is why they are the option of last resort.
At certain traffic levels it absolutely becomes worth everyone's while to do the passing track thing. And it'll probably come to that on the outer Fitchburg Line once Norfolk Southern swallows Pan Am's 50% stake and runs its own show. When Ayer and Shirley ever get ADA'd there'll be passers installed so they don't have to bother at all with mini-highs. And N. Leo will someday get a passer; main constraint there is the small home heating oil company that has an adjacent freight siding may have to get land-swapped elsewhere for sake of shifting stuff around. Norfolk Southern doesn't want to forever cut nuisance checks and buy extra insurance if it can avoid it. At certain point a one-time contribution for a permanent solve makes dollars and sense for them. We're pretty close to that threshold as far as the Fitchburg Line's concerned, since the double-stack clearance project is about 5-6 years from completion.
Haverhill Line as I mentioned has some tougher nuts to crack on available space around 3 of the 4 affected stations, but Pan Am's successors will almost certainly look at their growth curve in Portland intermodal and see rationale for paying in to get passers on the stations that can be checked off soonest.
And then a sliding scale by traffic levels from there on the other wide-clearance lines. The mini-highs on the Lowell and Franklin Lines don't take nearly the abuse of the Fitchburg, Haverhill, and outer Worcester and are in a different universe re: mutual pain threshold on maint and liability.
This is why GO Transit is just saying "fuck it" and doling out checks to Canadian National and Canadian Pacific to buy every single line on Toronto's commuter rail system, and AMT in Montreal is building a warchest to do the exactly the same with exactly the same Class I landlords it's sick of putting up with.
Sharon and points north, Attleboro and points south...sure, debate away on how to remove the crayon from Amtrak's brain.
If the freight operators hit the platforms and foul up the tracks, the MBTA can sue them for damages over maintenance costs and lost revenue. If the schedule's not robust to derailments - which it shouldn't be, because first-world railroads shouldn't plan around frequent derailments - then also for higher operating costs of the commuter rail equivalent of direct-as-needed. Unless there's an agreement somewhere that says it's the MBTA's fault if a freight train derails because it hit an obstacle that's like a foot away from the dynamical envelope, the MBTA has a clear-cut case.

Ah, but that's in the fourth-world west where the Class I's are the landlords on every length of rail. We don't have to deal with that garbage here in the states where Penn Central's big belly-flop put the states in ownership of outright majorities of their rail networks' route miles. As per those STB filings I mentioned, the rights and responsibilities and liability insurance for each party are crystal-clear spelled out. Buying the outer Worcester Line from CSX pretty much removed the last area of conflict in MA, and it's been a complete 180 in neighborliness since then.Hell, the reason the Class Is demand unreasonable track separation for intercity rail (UP with California HSR, CSX for Empire West pretend-HSR) is precisely that they don't want to pay damages in case their trains derail and kill passengers. It's part of a railroad culture that will do anything, anything, to avoid proper maintenance. See for examples this and this from the last years of the Milwaukee Road.

Caveat: Wachusett's cost includes the Fitchburg Line's new layover yard, since the current East Fitchburg layover (which is tucked around an increasingly congested freight yard) is tapped out of space and the Fitchburg schedule can't increase very much without new digs. The cost has ballooned to WTF proportions, but there's a bit more to that build package than a +1 station in isolation.The reason I'm pushing this is that the Wachusett station is $23 million, and total project cost is $63 million. It's several times what it cost to build Fairmount Line stations, converting the cost of raising all the platforms from a second-order term (around $400 million at $6 million a pop) to a more significant one, on a par with electrification or new rolling stock.
But...like I said, Mansfield passer isn't optional if you want full-highs at that stop because of that freight exemption. Mansfield's and Attleboro's primary industrial parks are all built around that mid-afternoon CSX local, and there an I-495 situated truck transload served that keeps a lot of big rigs off the two-lane state roads in the adjacent towns. It's not big money for CSX writ-large or Massachusetts writ-large, but it's a profitable job and looms largeish for the tax base of these smallish towns. Not the place to be considering any "go away" blank checks to expunge the clearance exemption, especially since it's a non-factor for passenger slots.The Master Plan was what made me realize Amtrak was irredeemable; that unwillingness to use smart scheduling to reduce the amount of concrete pouring is a big part of it.
And thankfully, it's not even funded. Amtrak seems to mostly care about Gateway nowadays, anyway. So no, it's not spilled milk. It's a wishlist on a par with the New York Second System.
