Category:Extensions

Extensions are critical to growing a TrainStation "business". When you start playing TrainStation, your station has only one rail for trains and one short street for buildings. You can dispatch only four 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 two more stations and upgrade them, too!

Extensions are located in the Shop, on the Station Extensions and Themes tab.

There are ten types of extensions in four 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.

 If you buy the Stock Exchange ( special building) you will receive a  20% discount on all future purchases of themes and extensions. The Discounted Cost column in the tables below shows the prices of items when the discount from Stock Exchange building is active.

IMPORTANT NOTE: To receive the discount, ensure your Stock Exchange is placed on a street in your  PRIMARY STATION before you purchase an extension. You will not receive this benefit while Stock Exchange is placed in Storage or on a street in your 2nd Station or 3rd Station. (This info is probably not accurate, as it's stated in the forum that you do not lose the benefits of this building if it's on the 2nd or 3rd station.)
