lol yea ok so how bout you just tell me how you do it and then i can have a betta life at this dam game lol
		 
		
	 
 
So you really want me to divulge the secret of signalling, aye. Signalling isn't that bad really. 
 
I have found in the past that the AI does not follow signalling the way you think it should go. So having said that, I use the following setup which works pretty consistent through out the layout. This may not be proto-typically correct, but it works consistently, which is what I want. Besides when you think about it, many railroad companies had their own way of doing things such as signal systems and placement, so my placement maybe what some company uses somewhere.
 
Using NorfolkSouthern's Searchlight Signals, which I find look and act somewhat realistic compared to Auran's default signals which look to bright and flat.
 
Use Type 4 --- Absolute signals for stopping at junctions where two line converge.
 
Use Type 5 --- Permissives in between.
 
Use Type 6 --- Two headed diverging signals at the junctions. These face back at the Type 4s and sit on the single line.
 
The Type 6s have both the lefthand as well as righthand drive as well as gantry type signals. There are also heads only so they can be placed on the backside of other signals.
 
There are a couple of other signals worth mentioning. Type 8 and non-Searchlight signals such as the dwarfs, which are used in yards and on sidings.
 
Type 8s are found on junctions. I use them when I have big diverging routes and cross-overs. These are gantry-type signals and have 3 heads.
 
The dwarfs come in various styles. For my route I use the CNR dwarf signals - both the LH and the right-sided. They are used as absolute signals in yards and keep the trains from blowing out on to the mainline from sidings. There are also Type 2 dwarfs also from the CNR and some now for the B&M. These act like the Type 6s mentioned above, and work well where you need a lot of signals but don't have the room for them.
 
Now the question always comes up regarding the spacing of signals along the line. I happen to use a consist such as US Coal 3000T as a moving ruler. I place the consist down, and on one end I then place the signals such as the Type 5s. I then roll the consist along so that the end lines up with the signals and the upper end is out on the tracks somewhere. I then place a new set of signals. When I come to a junction, I treat these as seperate from the route-signals and I just place them where they should go.
 
There's something, which I forgot to mention regarding the spacing. Spacing has a lot to do with the line speed and the length of the trains. If you run long freights, then your signals will be place further apart. The train speed will also affect the spacing. With short fast trains, you may want your signals closer together so that the line can hold more trains on the route.
 
Hope this helps. This is by far from perfect, but the method works for me.
