Category:Extensions

''This page is about extensions, which now have a separate page from the themes. For themes, see Themes.''

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 station before you purchase an extension. You will not receive this benefit while Stock Exchange is placed in Storage or if it is sold.

Fleet Management
The Fleet Management category includes extensions that help you handle more trains in your fleet and handle them more quickly. You can see most of these items on the Trains screen. To access your trains fleet, click on the banner marked Trains in the top left corner of the game screen.

Rails
A station's Rails support train traffic in and out of the station. Trains will stop on the rails and wait for the player to dispatch them or unload their cargo. Adding rails increases the efficiency of train operations. The more rails a station has, the more trains the player can load and unload simultaneously.

The game begins with one rail. Players may purchase up to 3 more rails. Together with the original, these comprise a maximum of 4 rails available for steam, diesel, and electric trains. Players also may acquire up to 2 rails for maglev trains. Each rail extension purchased includes a free train slot.
