Yes that would be possible. I actually made your suggestion into a mod. Should be releasing soon.

Moin thanks for the great mod can it be that in offenbach no more people get on and off? because I drove a service and since then the platform in Offenbach Ost is completely empty even with the Ki trains no people get off. and also at the remaining stops from Hanau to Offenbach no people get on or off.

Hm. Seems I need to Test if that is the case or if it's without the Mod installed as well. I didn't notice that before. When testing the Mod I did an early mornig run so nothing seemed off to me. But normaly a Formation swap should Not change the passenger behavior. At least to my knowledge.

I drove and then completed the timetable ride and then continued playing in the free game and the platforms were empty and nobody got off the Ki trains.

So, I've tested the whole thing again a bit more thoroughly. In Mülheim (Main) no passengers are actually getting on or off. At all the other stops everything works as it should. The problem in Mülheim (Main) is also present in the base game (not a single mod installed).

Ah ok thanks again for testing I have tested it in the free game so on foot and there the people do not get in with me. I have now reinstalled the mod and now everything runs as it should Thank you

The only thing different in these files compared to the others i uploaded is that more than one Plugin Directory is packed in the same file (so you only need to download one file and have all three timetables). Or it could be something about the Asset Registry file? What ever the case may be I can not test that because I only own the steam version of TSW 5.

I think it must be something with the different folder stucture on Gampepass vs Steam. Im not a modder by myself, so cant really help.
Gamepass Version has a separate folder for every DLC you can buy, i. e.:
D:\XboxGames\Bahnstrecke- Frankfurt - Fulda\Content\TS2Prototype\Content\DLC
D:\XboxGames\FrankfurtSBahn\Content\TS2Prototype\Content\DLC
and so on....
In which of the separate DLC folder you drop the pak files seems not really to matter, God Mode i.e. I can drop into just one random picked DLC folder and it works for every route I own.

On Steam you have one DLC Folder where you dump all the .PAK Files you download and all the official DLC .PAK Files are stored in there as well.
The Path within a .PAK File looks like this: "TS2Prototype\Plugins\DLC\DLC_NAME\Content".

In the case of my mod I have one .PAK File and within 3 Folders in the same spot as "DLC_NAME". Them being for 3 different Plugins I am trying to replace at the same time (CRG_DB_BR101_Expert_Gameplay; FrankfurtFulda_Route_Gameplay; FTF_DB_BR111_Gameplay).

I wonder if that 3 in one package is the problem here.
Do you have the same issue with the "BPH MA only Salzburg-Rosenheim Dostos 4 german Routes" mod?
That one also uses the all in one format.

It also could not work if you don't own the Expert BR 101 or BR 111 Timetable. Maybe the game trys to load them in because the mod links to them, won't find them and therefore prevents the mod from function correctly. I would think in that case the game just crashes but it seems the game just ignores that and loads in fine but shows nothing because of it.

That's my theory at least. I'm gonna test that in fact. And if that is the problem I'm gonna question why the game works like this.

You can choose between the 430 replacement and the 423 replacement. The IC replacement can be installed independently.
