Didn’t a mod get it kinda working not that long ago? The trains were still moving and the stations were there on release, CDPR just put walls up or disabled the doors to the stations/trains. They’re a little jank to ride but it was doable. Felt like CDPR just decided focusing on cool cars was more worth the effort
Seeing most of the fixes go towards that instead of immersion kinda... You'd think they highlight those immersive aspects more. The mods are sure as hell all about immersion including working stock markets and such.
