I've tried to follow one of the examples, but I may have messed up the setup because in the images in the linked thread, the trains drive on the left-hand side. My trains drive on the right-hand side. More specifically, I have tried to re-create this particular inline station setup (taken directly from the above thread).
This next image is my recreation of the above, but with trains driving on the right (the image above has trains driving on the left). The train needs to go into the station on the left, but instead, the train says NO PATH. What's wrong?
