Passengers Not Getting Off Train.

So I know TSW passengers are janky to say the least but I noticed something that's pretty immersion breaking, for me anyway.

On every non-dovetail games routes (eg Just Trains, Rivet etc) passengers never disembark the train. They will board at stations but no-one ever leaves. (Tried on Blackpool branch, west Cornwall etc)

On dovetail routes (Brighton main line, Cardiff, east coast way etc) they embark and disembark normally.

Try it for yourself. Why do the passengers on non-dovetail routes never leave the train??

I'm playing on PC TSW5, no mods, vanilla game.

 

Now this is something I have taken the time to look at. I will see what happens on my SB series X

 

Happens even on DTG's own routes.

It's a core issue with the passenger system.
