That's always a little tricky! Usually I read carefully the directions given by the maker of the asset. Sometimes it is immediately recognized and sometimes you have to 'play' a bit with the pedestrian paths to get a correct connection. There is simply no ready-made solution available. But after a few game years it suddenly works and the AI ​​knows how to make a route to it. Most platforms and buildings can be dragged into a footpath without being noticed.

Yes, I recognised those two buildings, thank you btw. Just a question, I've built a similar train station (with other assets) but the whole thing doesn't work. How did you make it functioning?

No problem and those 2 brown building are they Old post offices also from the workshop.

Thank you man!
