Here is an answer for you to think about: First lets set one thing straight, like any other Operating Sys, Windows, Apple, Linux all have issues with applications not working or not programmed correctly, with Trainz, I started with Trainz Driver 2 for Ipad. This was 2014, from that time on, I had some Faulty Assets to deal with, in my case because I'm not and never will be a Asset Creator, the Choice, find some one to fix said Asset, or Delete it and replace or work with out. As Trainz evolved, my Faulty Assets increased exponentially.
Why, well for one good reason, new Trainz Versions, more restrictions with how Assets were made, LOD, Level of Detail load against the Trainz Program. So what worked on more than one version of Trainz eventually Versioned out, and would not be supported unless the Auther of said Asset, redid, fixed, upgraded an older Asset to work with newer versions of Trainz. Be warned, it is a lot of work to go thru an older Asset and fix, recreate etc.
Not every Author is going to do this, and this is very time consuming issue! Let alone, many Authors have passed away too .RIP
A fair number of us run 2 or more versions of Trainz, and fairly well know, which older Assets work with which Trainz Version.
For me, I love TRAINS 2019 Platinum and I really like Trainz 2022 PE (Platinum) I know exactly which Routes will work in either Trainz, just last week, I had a huge Merged Route with missing Tracks I couldn't located on 1/4 the Route, my missing Spline would not work in 2022, however in 2019 it worked quit well. End result, I use 2019 and not put up the hassle of 2022 issue with missing spline utility.
But to be fair with 2022, 2022 surpasses 2019 in many ways, it's faster on DBR by 50% or more, you can do a whole lot more with
TRS22 / TRS22PE or
Trainz Railroad Simulator 2022 / Platinum Edition, is the latest version of the very popular simulation game,
Trainz by N3V Games. Pre-orders for TRS22 commenced on December 9, 2021 and coincided with a TrainzPlus Beta upgrade on December 21, 2021, which included
Surveyor 2.0, a completely revamped interface for creating, building, and operating Trainz Routes. TRS22 Platinum Edition released on August 22, 2023.
On February 11, 2022, Tony Hilliam announced the release of
TRS22 "Early Access Edition" in anticipation of a late-March 2022 official release of
TRS2022. As external testing continued, extra time was taken to ensure a smooth official release which took place on May 31, 2022.
However with all the great features of 2022, you still have to deal with Older Assets that show Faulty, and or do not comply with Rules of Asset Creation, and it is a laundry list on what your Asset how your Asset Created.
Currently I have both programs 2019 and 2022 both Platinum, working on 4 Terabyte Drive, Drive Space is another strong, by all means more important to have enough potential room to grow you Version of Trains, with all the 100,000s of Assets you'll collect over time. My asset count at the moment, 780,000, also realize a huge Route can easily reach 1 Terabyte, not counting whatever Assets you'll add, Rolling Stock, Buildings Etc.
Now I must be truthfull every so often, I get a Route, Old or Newer, that simply will not work properly in either Version of Trainz, if I can get it working within an hour, I get rid of the Route. I have plenty of others.
As an initial advice, make sure you purchase the largest SSD, beefy Video Card you can find, most RAM for memory, I run 64 GB, 8GB Radeon, AMD Rysen (runs much cooler than Intel)
Device name ROG STRIX
Processor AMD Ryzen 9 8940HX with Radeon Graphics (2.40 GHz)

I hope this helps, and there are other much more learned Members here than me.
