→Block signals explained
On the left picture you can see our example station situation with incorrectly positioned signals. Each block is located between two signals / end of the track and colored with different color. Red is the station block, blue is the "entry" block, green is the rest of the track.<br>
In the real functional railroad with two trains, you will almost immediately hit the deadlock issue with the train. The problem is in the two-way signals on a single track. Very soon the trains will stay at one signal against each other. To avoid this, you can introduce some kind of avoiding track with one-way signals (right picture). You can notice that the station block is now split into two tracks with two one-way singal. One "entrance" signal, one "exit" signal. The incomming train will from the green block, to blue block. Then the train enters the station and blocks the red block. Next incomming train will have red sign on the entrance signal, because of occupied red block. The diference between left and right example is, that the train have a space to leave by the yellow block. This is effective enough on the low load railroads. For examples of how to use the signals, go to the [[Junctions]] page

''Crossings with not enough signals'' - the whole red area is single block and can be occupied by only one train. That will make that crossing very ineffective. For it to work better, there need to be 6 more signals (marked by green rectangles)

As practical example of the ''Not enough signals'', train could block itself in such block. For this train to move at all, there must be more signals placed in marked rectangles.
