They are used primarily to manage splits in the track and intersections where rails cross or join. What Are Chain Signals?Ĭhain signals are a little more complex. If you are going to have multiple trains using the same track you should be using signals, even if they are going the same direction. Signals prevent trains from colliding with each other if one is going faster than another or they are going towards each other. When and Why Should I Be Using Signals / Blocks? There can only be one train in a block at a time so they won’t collide. The first signal going into a block checks to see if there is a train in the block past it and will stop an oncoming train from entering that block if there is. Sweet Transit automatically color codes blocks when you have the signal tool selected so you can see where they are. What Is a Block?Ī block is the space between two rail signals. The train on this track runs left to right, a train going the other way will not see the signals and will crash into an oncoming train. Instead consider building a 1 way loop or two tracks side by side for each direction. You can have trains going both directions on a track, but I don’t recommend it. If the arrow is pointing the wrong way, you need to place your signal on the other side of the track An arrow will point in the direction your train should be going. The side of the track you place the signal on determines which way you want your train going on the track. This is useful, and pretty much necessary, if you would like multiple trains on one track or if you have tracks crossing each other. What Is a Rail Signal?Ī rail signal is used to tell an oncoming train when there is another train on the track ahead, and to stop it so they don’t collide.
