How to play: Signals 101
Having trouble understanding how signals work? This is the guide for you. This guide is for those who have already have a basic understanding of how to place rails, stations, depots, as well create trains and routes but need help making sense of signaling. If you don't know any of those things check out How to play: Your first train route.
Many of you are already somewhat familiar with some type of signals from your daily life such as traffic signals. However locomotive signaling operates somewhat differently than road vehicles. This guide will attempt to practically explain how signaling for railroads works in voxel tycoon.
What do signals do?
Signals tell the locomotives where they can and cannot go, they allow for the train to find it's path to it's destination. They allow for intersections and help prevent collisions.
Signals do this by diving the railroad into sections called blocks. The mechanics of the game do not allow multiple trains on one block. There is no visual representation in the game other than the rails and signals, but when you build rail you are creating a new block. Every piece of connected rail will make up that block. So if you have a railroad with no signals you have a 1 block railroad, which means you can only have 1 train. Later on in the game you will have more blocks than you can count so don't worry too much about how many blocks you have. However a general rule of thumb is you will always need more blocks than trains so they can move around.
