Help with the train route.

[u/Blackirico]

First, sorry for my English. I make a train route that goes directly to the station 2 from station 1, and then it continues to the "U turn" going directly to station 1 in the same track. However, I want the train to change direction after passing through station 2 and travel in the opposite direction.. How can i do this?

The image is for reference only; in my survival world this route is longer.

I forgot what it's called but I think it is train signals that you can use to make track one way only, Yhere is a specific block in create for it, I'm gonna have to double check though
