Category:Extensions

When you start playing TrainStation, your station has only but one rail for trains and one short street for buildings. You can dispatch only 4 trains at a time, and you can't dispatch diesel or electric trains at all. Extensions allow you to change all of that. With extensions, you can make your station bigger, dispatch trains more quickly, and discover new technologies that unlock more parts of the game. You even can build 2 more stations and upgrade them further!



Extensions are located in the Shop, on the Station Extensions and Themes tab. There are 10 types of extensions in 4 main categories: Fleet Management, Population Management, Technology and Storage. Most extensions have multiple levels of upgrades. All together, the game has over 170 extension upgrades available.
