@Tossi, Pretty sure I mentioned in my guide that it would only work for 2 trains using the route, if you had four trains then you would have two passing loops.
And I quote >
“It’s important to note here that if you have two trains running on the line, you will require 1 passing loop somewhere along the middle of the line. If you have four trains running, you will require 2 passing loops at a third interval on the line. So essentially, once you have two trains running, for each additional train you’re running, you will require an additional passing loop along the line. At a ratio of 2 trains to 1 passing loop, so 8 trains will be 4 passing loops.”
Thank you for your input but clearly you didn’t read the guide in its entirety before you posted. 🙂
