In particular, the way two-way tracks are designated is exactly the same. The chain and block signals in Voxel Tycoon are almost exactly the same as the chain and rail signals in Factorio. This way, the pre-signal grouping cannot be blocked forever as long as there is enough space after the exiting regular signals to fit each train.Ĭomparison with other games Factorio If this train needed to pass a pre-signal to enter the offending block, then it must be able to leave the block, thus freeing the original train. Trains can pass an initial pre-signal, only to be blocked at another pre-signal by another train. when it wants to go to a station in the middle), but there is no eventual exit after the train's path, the train will not go through. If a train does not need to pass completely through a sequence of pre-signals (i.e. The pre-signal will be green if all possible paths are free, yellow if there is at least one blocked and at least one open, and red if all paths are blocked.

This is usually used for keeping intersections free and distributing trains among platforms.
The bottom train will be able to pass through the intersection with the help of the pre-signal on the right track.Ī train will pass a pre-signal if every block in the train's desired path up to and including the next regular signal is free.
