I wanted to learn Colonel Will's way of trains but i have porblem signaling junctions. I build this: http://i.imgur.com/Y5nEAaM.jpg and the signal i marked with red rectangle makes the train go "no path". How do I put signals in junctions like this? IF i remove that signal it works but I only have 1 train. Wont removing this screw up things for more trains later in the game?

Signals should always be to the right of the train. A signal on one side is equivalent to having signals on both sides, with the other side constantly red.
The signal on top is on the left in the direction the train is coming, so it is considered to be always red. Move it to the other side of the same track to solve the problem.

So if i put signal on one side of the track i make that track unidirectional? If i want trains to go both ways on track then i need to put signals on both sides?

Exactly. A single signal effectively makes a one-way track.

Edit: To make a two-way track, make sure the signals are coupled - they need to be exactly opposite eachother, and when one is highlighted the other will be highlighted as well, letting you know they are indeed coupled.

Thank you. Now I understand it completely. Its easier than I thought initially.
