I currently have an intersection of trains. 4 go parallel and 1 perpendicular. I would like to let the 4 parallel trains all go if they approach the intersection at the same time. However, they all stop until one train gets through. I have to admit I'm not so great at signals, so I'm sure I'm doing something wrong. Here's the layout:
This is the perfect opportunity for path signals. They show the train which routes are available and therefore the parallel trains will only have to stop when the perpendicular path is taken.
