The days of interchangable locomotives and cars are gone, the days of universal ownership (like the PRR, NYC and NH being able to find cars in Chicago, Pittsburgh etc for overflow in New York) are also gone and with every commuter railroad basically using something different, this is what you have.
In a sense, what we could use is a 21st century President's Conference Committee for the Northeastern commuter rail operators-- to come up with a unified design or set of designs (say, one for single-levels, one for bi-levels) that could be used on every system from VRE to MBTA. In the long run, that would probably reduce unit costs for everybody.
On the current topic- the only thing I could see making marginal sense would be a dual-mode version of (or replacement for) the BL20GH's on the Wassaic, Danbury & Waterbury shuttles that in a pinch could operate into GCT.
Well...we kind of do on the coach side. They're called Comets and Bombardier BLV's/MLV's. The various classes of NJT/SEPTA Comets, MNRR/CDOT Shoreliners, and MBTA BTC/CTC-1's are all extremely similar. And nearly every bi-level coach on the east coast from NJT's MLV's to the MBTA's Kawasakis and Rotems to MARC's Kawasakis and MLV's is based off the 35-years-proven Bombardier Bi-Level design. I'm sure even the miniaturized MLV form factor is producible from other vendors; it just hasn't been around long enough for anyone to tap a non-Bombardier source. Everybody's got their preferred door and interior configurations, so that'll be a defining difference. But it's not a very big one, or one that affects procurement costs very much. And except for LIRR with its extra signal aspects, all control cabs are going to have the same cab signal + ACSES gear.
For locos, each system is going to have different needs. The MBTA is going 4600 HP with its next order because it's got humongous 6-7 car bi-level trains to haul on its heaviest-use lines. An HSP-46 would be silly overkill for MNRR pulling 3-5 single-levels out in branchline territory. MNRR and LIRR are the only two who need shoed dual-modes. It's a reasonable assumption that the P32 and DM30 replacement order is going to be synced between both roads for economy of scale. NJT is the only one that needs overhead duals, and they've got their fleet commonality set in E mode with the ALP-46 and ALP-45DP being single-source sister models. MARC and SEPTA have much more limited scale and maintenance ability for electric push-pull; they use what Amtrak uses, and will probably keep doing so if they stick to status quo.
Same with EMU's. M8's have no precedent anywhere in the country because of its unique panto + shoe power inputs. M7/M9's are captive to only the MTA roads at LIRR clearances. They have to be what they are. NJT Arrows and various generations of SEPTA Silverliners do share a lot in common, and the SL V's are going to Denver. That's the closest thing to a generic single-level EMU platform in this country, much like the Comets are the closest thing to a generic single-level coach. If NJT does another class of single-level Arrows they'll quite likely be cousins of the SL V's (hopefully with Kawasaki et al. at the helm instead of Rotem). If MNRR and NJT opt for MLV form factor EMU's I bet they'd be panto vs. shoe cousins from the same builder. It's safety in manufacturing scale for a form factor that's never been EMU'd before. If either road revisits the very different Bombardier power car + generic MLV coach idea, they'd be cousins too for the same reason. And BBD would be able to market the same power car make in the full BLV form factor as bait for the MBTA and GO Transit electrification given both roads' huge coach fleets of BLV + clones origin. I don't expect much divergence in East Coast EMU's the way economy of scale drives some of these massive-size orders.

For straight diesels, you could argue that generic is better than customization. The HSP-46 is such a customized beast that the T had to hire hordes of subcontractors to manage MPI on the design. It'll be worth it if those prove to be good engines with mass market appeal, but the effort is questionable if nobody else ends up buying them and it becomes an agency-specific unicorn (even if a good one). You could argue the same about the Brookvilles if they don't get more buyers. Ditto the PL42's since everyone else took a pass on them. The failure of the DM30's to do E mode as well as they should has basically rendered the DE30's an evolutionary dead-ender. The T botched its GP40MC secondhand buy by retrofitting those otherwise great engines with quirky, unproven computers that never totally worked right (although it's a lot better than it used to be), instead of just sticking with what's bulletproof with everyone else's Geeps. These should be teachable moments. Unfortunately, they haven't been.
Those specific examples aside, there is a lot of commonality in the diesels. Those still hanging onto older models like the T/NJT F40PH variants; the T/NJT/CDOT Geep variants; and the MNRR/NJT/CDOT/Amtrak Genesis variants are using the 3 hands-down most ubiquitous passenger loco classes of the last 40 years. MARC's new MPXPresses are the single most ubiquitous class of passenger locos in active production. You could argue the T would've managed its risk better buying stock MP40's or having MPI build a generic mass-market MP46 instead of swinging for the fences on the all-new HSP-46 class...but we'll find out the wisdom of that decision soon enough. It would be great if the MPXPress eventually offered a shoed dual; they can fit MNRR/LIRR clearances. The worst you could say about diesel fleets in the northeast is that NJT needs to get its house in a little bit more order cleaning up its roster of 7 different straight-diesel makes from 4 different classes, but except for the PL42 oddities all of them are generics. Hopefully when they do prune and replace the portion of the diesel roster that's not being supplanted by overkill ALP45's they stick with some tried-and-true new make like the MPXPress or Amtrak's next class (F125?) rather than designing another PL42-like unicorn.
--------------------
The only thing that really has to be done is each individual agency needs to rein in their respective customization fetishes. My local reference point is the MBTA, which has gotten anal retentive to an extreme about micromanaging every knob and contour in the cab and every function in the onboard computers that Rotem and MPI are years late in the latest coach and loco orders. That's not helping, and it's bit them in the butt too many times before. But all of those are cultural tendencies at the agencies. Every one of them has different internal politics. It's the price of doing business with clumsy regional authorities.

Now, the one vehicle type where there desperately needs to be a PCC-like committee are DMU's. The FRA-compliants market is so sluggish and lacks scale. If you buy from one vendor, you are stuck with that one vendor's class. They can't intermix. There is no common type of dead trailer that you can add that works with different classes, and they can't pull off-shelf coaches for the same reason EMU's can't. You can get burned like Colorado Railcar's buyers did if the manufacturer pulls out of the market and leaves a fleet orphaned, unexpandable, and unable to trainline with any other make. No vendor has done multiple generations of one class compatible with each other. It's not certain that a market in its infancy is going to have 2nd-gen vehicles compatible with 1st-gen like the M2/4/6 and SL 1/2/3/4/5 EMU's. It's entirely possible someone like Nippon Sharyo is going to have to go half-back to the drawing board for their next gen to perfect the design, and orphan the first gen. Even if the first-gen turns out pretty good; it's not known how much evolutionary juice that one current design has got for the future.
At least with the RDC, every make in the class with compatible with every other make. They were modularly convertible to dead trailer. It was an eminently expandable fleet on scale. We quite badly need something like that. It's a shame the SPV-2000's and Metroliner EMU's were such lemons. Between those and the Amfleet Budd had the beginnings of a converging DMU, EMU, and coach lineup whose later generations could likely play with each other. That's the kind of thing a "PCC" MU could bring to the table. I just don't think getting all the manufacturers to the table to agree on a common platform is realistic today. If a de facto standard emerges it's because the Bombardiers, Kawasakis, Alstoms, and Siemens' of the world start mass producing them and converging on an
approximate and de facto standard much like the coach market with the BLV/MLV form factors and the Comet class. It remains to be seen if approximate standard is close enough for vehicle interoperability. Most likely that's gonna take a while and a couple generations of modern vehicles to perfect. And so far all those big boys are standing on the sidelines not overly wowed by the FRA-compliants' immediate prospects, so we're still barely at the starting gates.
