I am thoroughly confused on setting up signals for a simple diamond crossing for my route. In the pic below my route runs east and west. There is a single line (dummy) that runs north and south.  So far so good.  How would I signal both routes? I was considering a interchange from the eastbound track to the northbound one. Now, I am in WAY over my head. 
I think an interlocking tower is needed. But when I look to set one up, the directions are like I was reading an ancient foreign language. Even though the north-south line is a dummy, I'd still like to signal it like it's a real functioning line because I may expand things there. Help
