It's basically a visual version of the classic deadlock conditions. Chain signals create dependencies between locks, and the locks themselves (the rail signals) have to be granular enough to keep large sections of the rail network available to acquire. The confusing part about the chain signals is the blue state: the train will use its pathfinding to read forward of the signal and it will move if the path it needs to take is available. You have to look forward of the signal to see if the rail signal for the path the train wants to take is green or not.
