That may explain why the GP40P's had the heaviest axle loading for four-motored locomotives.
Since CNJ had Trainmasters C&O looked at SDP40s on Trainmaster trucks but B&O had few sd40s. So they decided on gp40p as a better idea. Gary
On the Great Lakes, I believe there's still a tug boat or two with OP's inside.
Otherwise, the commercial era of FM OP's on Great Lakes vessels ended in 2018 with the final layup of the freighter Algoway and the departure of the Stephen B. Roman (A cement carrier converted from a retired package freighter) under her own power to Aliaga Turkey for scrapping. Last of a long line of merchant ships on the Great Lakes that utilized this family of Fairbanks Morse engines.
At least the Canadian and American Coast Guard services keep the sounds of these engines alive on the Great Lakes, for now. The CCGS Griffon which handles icebreaking on Lake Ontario and the St. Lawrence still has her four 38D8-1/8-12 diesels. And the US Coast Guard stations most of their Bay class tug icebreakers around the Great Lakes (Each powered by a pair of 8 cylinder OP's).
Edit: And of course one can still hear these sounds in their native habitat several times a year aboard the preserved Gato class submarine USS Silversides in Muskegon, Michigan.
The problem wasn't the heat so much as the firing pressure causing fatique failures.
To my knowledge there are no river tow boats with OP engines. The navy and coast guard are about the only marine engine customers.
You mean it was the 251 cylinder heads cracking, right?
I was surprised nobody looked into supplemental water passages fed by a separate pump that would only come into action to cool the head to 'average' normal range when under heavy sustained load.
Were there issues with overheating or cracking in the OP engines used in river tows?
Its funny how FM emphasis on how reliable their cylinders are now. About 40 years ago on the river they were known for cracking under the high horsepower loads that towboats are subject to. At the time they were a threat to EMD over their supose fuel effciency.There was a proposial to redesign a cylinder head for Alco. Part of the solution was to dial back the maximum power so the heads would run cooler. The average voyage time from NOLA to St. Louis took about 2 more days or 10% longer.
Interestingly enough, to preserve sales of the 251, the 'railroad' use of the FM OP design is officially restricted in North America!
Paul Milenkovic Correct me on this, but aren't ALCo engines still in service and even sold for marine applications such as river-barge tow boats?

More important still is the continued presence, and more specifically the improvements, of Alco 'technology' on Indian Railways.
I refer only to actual Alco production (not the subsequent career of MLW in North America and its effect on the aftermarket) and to the specific environment of what became New Jersey Transit. Note that the U34CHs themselves were taken out of service in the early 1990s, and have now been gone nearly a decade longer than their very long and productive service lives; I don't think a product by an orphan builder would have been kept running by a state agency for this prolonged a period. On the other hand it is quite likely that various tourist roads would have found C430Ps at least as attractive as transplanted FPA-4s, and operators like Delaware-Lackawanna that have remained 'Alco-centric' would have found homes for others. I have not followed up the 'export market' for Alco power, but my understanding is that many units succumbed to what might be called "Starship syndrome"; certain parts of the locomotives had high resale value, and the operation of removal of those components rendered 'the rest of the locomotive' functionally unfit for sale as anything but scrap...
Overmod BEAUSABRE Turned out that "Every Model Different" was interested, so the C430P went back to the files. Perhaps not a bad thing -- the GP40Ps have had more lives than a cat, in some very demanding service. Nothing Alco-engined would likely have seen anywhere near that service life...

I guess the 567 and 645-engined EMDs were the Energizer Bunny of locomotive -- keeps going and going, but could ALCo really be counted out?
I read in Trains Magazine about Delaware and Hudson operating a stable of old ALCos and how their chief mechanic was an "ALCo whisperer" to know how to keep those locomotives in service. ALCo locomotives were not necessarily worse than EMDs, they were certainly different and a person had to know their quirks to keep them repaired.
Of the legacy steam-era locomotive makers, maybe ALCo stood a chance if their partner GE hadn't betrayed them? Correct me on this, but aren't ALCo engines still in service and even sold for marine applications such as river-barge tow boats?
If GM "killed the electric car", what am I doing standing next to an EV-1, a half a block from the WSOR tracks?
BEAUSABRETurned out that "Every Model Different" was interested, so the C430P went back to the files.
The problem was that NJDOT had an agreement with the B&O that the railroad would underwrite the purchase and would take the locos off the state's hands if the CNJ's commuter service sailed down that ever popular waterway, the tubes. Not unnaturally, the B&O insisted that locos purchased be compatible with its existing fleet (hence, they were painted blue instead of green, had easy to overpaint CNJ lettering, were numbered as part of the B&O roster and had to be B-B units). BUT, the B&O hadn't bought a non-EMD unit since Baldwin went belly up, so it was a forgone conclusion that the locos would be a derivative of EMD's GP40, if they wanted to bid on a thirteen unit special order. Turned out that "Every Model Different" was interested, so the C430P went back to the files. As far as the U34CH's went, they were for the E-L, which already operated GE's, so no problem.
In itswn way as beautiful as the EMD E5 and E6, and yet says power as well as speed. A beautiful painting. too!
Overmod Speaking of the Alco diagrams, here's one of them and a great deal besides: https://web.archive.org/web/20150304071338if_/http://www.gilbennett.com/anatomy-of-a-painting.html! Unfortunately the original Gil Bennett link to his famous painting of C636Ps has been taken down. But the discussion about his painting it survives in the Internet Archive for our enjoyment. Five minutes comparing this diagram with one of an FPA-4 will tell you much of what you'd need to know about logically making a cab-unit C430P... note the space available for two steam generators that could easily be used for gensets, or removed if a GTA-9 equipped for HEP were provided... wouldn't it have been nice if LIRR had bought an order of C430 cabs and proceeded to build those converted FAs for the other end of the trains...!

I can't lie.. That looks like one impressive passenger unit. Had ALCO got around to building a prototype.. It would've been something to see if it could go up against the FP45.
Overmod I believe that the C430s with dynamic had a similar dynamic brake relocation, apparently with three slots (see this model: https://www.bowser-trains.com/images/Loco/C430/24192.jpg the GB&W model, which did not have DB, shows the difference on this side at least https://www.bowser-trains.com/images/Loco/C430/24196.jpg I always presumed this was because of the intercooler location, but the question then arises if there is room to package a SG there with the DB relocated. As you are the premier authority on the C636, the intercooler arrangements were revised on that locomotive, and I wonder if there were drawings for a "C436" that would show the corresponding arrangement on a shorter frame.

The equipment layout in a C430 is exactly the same as that in a C630.
The C636 equipment differed in a number of respects from the C630, but it occupied exactly the same space. So a C 436 could have been built. But only about two thirds as many C430s were sold as C636s and the whole operation was winding down by that time.
There is no room for a steam heat boiler in a C430 apart from in the short hood.
Alternatively a C630 frame could have been used with four wheel trucks, since this provided a space which was usually used for dynamic brakes, but like the NdeM C628 could be used for a steam heat boiler, but requiring the dynamic brakes to be relocated.
While there is a superficial resemblance externally between a C630 and C636, the airflow was entirely different, the 636 taking the engine air in at the front, passing it through the frame under the engine and up to the turbocharger on the rear of the engine. The C630 (and earlier Century series) had a separate air intake at the rear for the engine. The M630 and M636 also fed the engine air under the engine, but it had no separate intercooler radiators, although large air intakes were located forward of the engine.

Overmod Talk about shoehorning hoods on a frame... Note the length required by the split tank arrangement.

Note the length required by the split tank arrangement.
I assume that 8324 is a C628P.
Like the C636P, the dynamic brakes which were a vertical stack behind the electrical compartment have been replaced by the steam generator and in turn, the dynamic brakes were moved to a "bathtub" arrangement over the engine, as indicated by the two rectangular air intakes over the engine.
This problem of both steam generators and dynamic brakes resulted in the "hammerhead" RS-3s where the hood did not allow a dynamic brake unit to be mounted over the engine.
CSSHEGEWISCH A C430P for suburban service would have to be redesigned similar to GO Transit's GP40TC's, which were GP40's on an SD frame to get the extra length needed to fit the HEP set.

CN rebuilt some RS-18s with HEP around the same time. The genset went in the high short hood, which was also extended to occupy the front walkway.

CSSHEGEWISCH The various six-motor Century designs included space behind the cab for a steam generator (or possible HEP?). I believe that NdeM received C628's with steam generators.

Chihuahua Pacific #904 and NdeM 8322-8331 were the C628s built with steam generators. Data from Extra 2200 South #47 page 22.

Lack of standardization was not one of Alco's issues. Consider that the C420 had a V-12 inside which allowed for the longer nose while the others had V-16's.
I love discussions like this. The C-430 rides on a longer frame than the C-424/425. Also different from the C-420. Lack of standardisation was one of Alco's issues.

Note however that we're explicitly discussing a C430P. The freight version of this was already visibly shoehorned onto the C425-length frame, and while I don't know for certain I would doubt that there is reserved space behind the cab without lengthening the frame.
On a commuter unit you might get away with using a smaller fuel tank, and of course with HEP, disposing of the tankage for SG water, to keep the weight within four-axle capacity. But that would impair potential use in freight service (which I expect for a C430P in that era to be long Alpha-Jet trains or equivalent, meriting large tank and carrying capacity as for the EL use of the 'SDP45' length of frame for some of its units). So a longer frame would be expected.
SD70DudeWould the roadswitcher C430P have needed a high short hood to house the steam generator?
Both LIRR and Monon put the steam generators in high short hoods, but examine the arrangement on the former:

Now remember that the engine on a C430 will be longer by at least the two cylinders in a bank, and this would affect the cab position and hood length, both of which are somewhat extreme on a production C430.

If you translate the SG dimensions in the C636P diagram over to this you will see the first problem; if you look at where the long hood ends and compare it with a GP40P you can see a second: I don't see a good way to build a SG passenger C430 without lengthening the frame, and doing so might upset the weight or balance to require at least one three-axle truck ... at which point a "C634P" designed comparable to the U34CH, with 720rpm HEP from the alternator to save length and weight, begins to look like a reasonable option...
It remains to be seen where "anything else" in the abbreviated high short hood would be relocated if some form of steam generation could be devised to fit in it (remember where they put the toilet on the LIRR 'passenger' MP15s?)
Would the roadswitcher C430P have needed a high short hood to house the steam generator?
Although not particularly relevant to this subject, here is what the C-636P would have looked like. This was taken from Alco diagrams and built in N-Scale. As previously said, a commuter version wouldn't be anything like this,but what a beast.

DanRaitzFor what it might have looked like, take a look at the MLW M420W.
The production C430s (NYC and Reading had them in the East, the latter experience highly relevant to CNJ options) all had conventional cabs, and reasoning from the EMD 'alternative' the major difference to convert a C430 to comparable commuter passenger service would be to extend the long hood. I would suspect this would retain notches but they would be the shallow ones of late production.
It occurs to me that the design might have advanced far enough to have produced internal-machinery or weight-balance diagrams that may have 'made it' to the Alco historical society's records.
