New Player Question

So I’ve noticed from posts on this subreddit, such as this one - https://www.reddit.com/r/subwaybuilder/s/xkV7Q7rrct - that you can have multiple station building under the same name, acting as the same station, and I’m presuming passengers can transfer from one line to another with this.

I’ve built stations near to each-other (with different names), but passengers rarely transfer between them, always by walking it seems.

How do I go about making them one and the same station?

I’ve been here noobing it away trying to pummel multiple lines all on the same set of 4 quad tracks, and this would change the game for me if I knew how!

Any help is appreciated, I hope I’ve explained it well.
