AFAIK, there is no permanent solution available.
Water cooling via an AIO (as I do) may give you better cooling headroom and peace of mind if not doing so at present. I also find running the better optimised 64bit DX12 version of TSC provides lower CPU/GPU temperatures.
Edit: Just noticed you are using an AIO for cooling, I would check if mounted correctly but none the less, your 7800X3D will run hotter with TSC than other games you play.
I experience the same with my Arctic Liquid Freezer II 280 AIO.
Best.
'Compared to the first-generation 3D V-cache processor, the Ryzen 7 5800X3D, the new Ryzen 7 7800X3D has a 500MHz higher max boost clock, and the Ryzen 9 7950X3D has a 1200MHz higher max boost clock because of the mixed CCD configuration. AMD states that the Ryzen 7000 series, especially the models with many cores, have high operating temperatures by design, which don’t pose a problem for their performance and reliability. For the Ryzen 7000X3D models, the maximum Tjunction (TJMax) temperature is around 89C under intense multi-thread loads. The TJMax is the maximum safe operating temperature, not the absolute max temperature. In other words, according to AMD, there will be no issues with the CPU running at 89°C all day. For the multi-core 7000X models, this temperature is a bit higher, at 95°C.'

The temporary solution is to run a older version of train simulator. More specifically the 72.3b version which is the latest before the big upgrade. Using this version I get max temperatures of 60 even running hour long sessions.
You can look at this thread here on the forums to learn how to install older versions from steam

I dont know why it removed the link, but if you google install older train simulator versions you get a post on the official forums explaning it. Its not illegal.
however - and this applies to everyone affected:
Please, make a ticket to DTG, the more people do so, the better.
And if older version was OK, there is even a reasonable chance, that they will eventually fix it.
The OP did list the Corsair iCUE H100i RGB Elite 240mm in his spec. I must admit I have noticed about a 5-10 degree increase in cpu temps more recently too albeit with a 5900x and a 280mm AIO. Temps in game about 80 degrees.
I just had the same thing happen to me with my 5 years old PC. I took the PC to the repair shop and they replaced the water cooling system.
Temperatures are now 30 degrees lower and everything runs fine.
If this happens with other games, I'd consider getting your water cooling replaced.
Another thing that can happen with PCs is if they are located poorly in the room, they will overheat. Try moving the PC away from any walls, and for the love of God don't put it in a cabinet or other enclosed space. Try putting it somewhere where the air can circulate. Also keep it away from any other sources of heat (such as heaters) which may be switched on at this time of year.
Another possibility is the fans are not working, or possibly you need more/better fans to maintain a cool temperature. Also dust can clog up a PC, causing overheating issues.
I hope it was useful.

I experience the same with my Arctic Liquid Freezer II 280 AIO, although lower temps of around 60C within TSC's menu and around 65C within the game (DX12 Version) playing at 4K 120Hz max graphics settings. My GPU also runs cooler under TSC DX12, by around 6C.
Today's higher end CPU's (both AMD3DX and intel 13/14 Gen) run considerably warmer than older CPU's, that is a new concept to many still and will be for some time to come. They are designed and long term tested to do so safely all day and all night if required.
TSC's very old stodgy base coding that all CPU's/GPU's have to wade through, is the cause of extra heat generated compared to much more efficient modern game engines and coding. A ticket to TSC won't change that.

CPU can easily survive temperatures which will otherwise destroy the rest of the computer (CPUs are usually build to survive high temperatures, computer PCBs are not).
And this is a real concern and I have seen it repeatedly happen over the years - mainboards and other cards fried literally by overheating CPU, while CPU itself was still happily working (in a new mainboard).

The only long-term solution is this: let DTG know, that this issue exists and let them do the code fix (and this is just a regression in never versions of the game, it should be possible to implement a fix - if this issue was there in all versions, now that would be a real problem, but this is most likely fixable).
DTG will not be able to make your CPU run cooler. No harm will occur to your modern X3D CPU if it runs close to, or at its maximum TJmax, it is designed and tested to do so for as long as required, all day if needed. The only requirement being exactly the same for all CPU's and PC's, good adequate cooling, which you have.
Today's 'state of the art' higher end CPU's from AMD and intel, bear little or no architectural resemblance to older CPU's of the past. Far warmer in operation when working hard, but far more powerful, that is the trade off, which won't change.
TSC won't change either, it is what it is, a very old game that was never cooler running like some other old games from 13 years or more ago, or today's modern more efficient game engines.
As a PC builder, for myself and others, I actually use TSC as one of my 'stress testing' ways of ensuring any new build is working as it should cooling and performance wise.
Best.
The DEC Alpha AXP CPUs always ran hot. Alpha AXP workstations were unreliable as a result. You’d typically have 20% of them out of service at any time due to regular failures. Sun UltraSPARC workstations ran cooler and were more reliable.
The Intel NetBurst CPUs (Pentium 4 family) all ran hot. Intel tried to claim it was a good thing and boasted that they’d soon have CPUs running at the temperature of the sun. Of course it wasn’t a good thing, Pentium 4 systems had reliability issues just like Alpha AXP workstations, and Intel admitted they needed to focus on efficiency with the subsequent Core family.
Liquid cooling adds a whole lot of cost and complexity, and more points of failure. If you need to do that outside specialised situations you have a problem. If the CPU’s dissipating that much heat, it’s inefficient, and the power use alone is a cause for concern.
TSC has changed, as shown by the fact that version 72.3b doesn’t exhibit this issue on AMD CPUs. It’s one of the numerous regressions in the big update. If DTG actually cared, they could track down the issue and fix it. But the more people make excuses for them and continue to spend money on their products, the less incentive they have to improve the quality of their software.
Liquid cooling 'does not' add 'a whole lot of cost and complexity, and more points of failure'. Well reviewed and tested AIO's are well built and no more prone to failure than any other components inside a PC. One of the reasons why they are so popular now and increasingly so. I can assure you, if not recommended, Pro-reviewers like Gamer's Nexus and many other highly respected Pro-reviewers around the world, would not be reviewing and recommending certain AIO's on test and placing them in their own rigs and testing PC's..
You say: 'If the CPU’s dissipating that much heat, it’s inefficient, and the power use alone is a cause for concern'. Again, with respect, it appears you did not read the detailed linked article about the AMD 7800X3D CPU I provided, which under detailed testing, confirms it is 'very power efficient' in relation to its superb gaming performance. Something intel can not match at present times.
Today's world of PC components and CPU's bear very little resemblance to the past, which understandably, some have no choice but to still be part of. Modern PC's and components are not cheap in many cases, although price to performance gained far better than the past.
Best.
Yet they keep causing regressions, like this very issue we’re talking about. Version 72.3b and earlier don’t exhibit this issue. It was caused by the changes DTG made in this update. They definitely are in a position to be able to do something about it.
You’re adding a liquid coolant loop, with the associated pumps, etc. That’s much more complexity than a heatsink and fan. It adds more points of failure, including the coolant pumps, and the seals in the coolant loop. It adds more failure modes like corrosion in the coolant loop causing blockages and/or leaks. I’ve seen all of these things happen.
Reviewers get a somewhat skewed impression of products because they have a limited amount of time to test them. They don’t get to assess long-term reliability. You see this all the time in car and motorbike reviews. Bikes that get great reviews in terms of rider experience often turn out to be maintenance nightmares. Reviewers also often have a conflict of interest as they depend on goodwill to continue to receive review units. If they’re seen to be overly negative, they won’t receive review units. PC gaming reviewers have a particularly bad reputation when it comes to avoiding criticism of products.
I’ll take experience managing large numbers of workstations and PCs in business environments over reviews and gamers.
Price/performance isn’t improving anywhere near as quickly as it was in the past. Back in the ’80s and ’90s, “Moore’s law” was still in full effect, and there were massive gains in performance every year. This has slowed down substantially in the last couple of decades as we’ve approached the limits of semiconductor processes. For example compare a 6502 from 1980 to an 80486 in 1990. The jump is insane. Then compare a 2010 Intel Clarkdale (1st generation “Core”) to a 2020 Intel Tiger Lake (11th generation “Core”). The difference is nowhere near as pronounced. RAM sizes haven’t increased anywhere near as quickly, either.
You seem to have a very distorted view of the PC market.
