These trains may in turn cause other trains to wait, resulting in a slowdown of the entire system. In that case other trains will have to wait even if they are not going in the same direction.

This becomes a problem when a train starts waiting on an intersection. Every train will wait until the block in front of it is cleared, so trains are waiting for other trains. Using signals prevents trains from crashing into each other but brings with itself other potential issues. bidirectional on the left side, splitting into a right to left (upper) and a left to right track (lower).In the image, the tracks are from top to bottom: This can sometimes cause a "no path" error where the track appears to be connected, but part of the connection is a one way track. A train in automatic mode will not drive on a track if it would pass a signal on the left side unless there is also a signal on the right side at that signal. Trains are only allowed to go past signals that are on the right hand side from direction of travel. Signals are placed on the right side of the track. When a train is in the process of entering the block, the signal turns yellow for a short time before turning red. When a train enters the block, all signals going into the block will turn red. Rail signals (and chain signals) break up blocks, train stops do not.Ī regular signal is green when there is no train on the block behind it. The picture shows the block visualization, there are a total of eleven blocks. These colors are only for visualization: the color of the signal will be displayed on the lights of the signal entity. Rail blocks are shown with colors when a player has a signal in hand. Whenever a second train would enter a block that already has a train in it, the train will wait at the signal leading into the block instead. Signals ensure that only one train can be in any block. A regular rail signal protects the rail block after it, up to the next signal or the end of the track. To prevent trains from doing this, we place signals at intervals along the track and at crossings. Whenever there is more than one train on a track, there is the possibility that trains can crash into one another.
