OpenTTD intro screen

The main window, as seen above, offers the following options:

Game Interface

Once you start a game, you will be presented with the main Game interface, shown below. You will spend most of your time in this screen while playing. It has three sections: at the top is the menu bar, in the middle you will find the 3D Isometric Gameplay World and at the very bottom is the status bar.

The gameplay screen

The Menu bar

The menu bar has buttons split up into sections as described below. The sections are from left to right: "Game controls"", "Map information", "Company and industry information", "Vehicle information", "Zoom", "Construction" and "Other".

  • You can see what any button does by right-clicking on it in the game.
  • Most buttons have two modes of operation: single-clicking activates the default action, while clicking and holding opens a submenu.

Outdated content.png

Out of Date
This article or section is outdated. Some of its content may no longer be accurate due to changes in the latest release. Please update this article.
This section does not contain information about the tramways construction button

By clicking and holding the Railroad build button, a dropdown appears where you can select the railtype that you want to build. Similarly, the Road build button allows you to chose between normal road and trams (you need to have a tram NewGRF loaded first).

The Landscaping button has a dropdown to access the tree and sign placement windows directly, instead of via the landscaping toolbar.



  • Switch Toolbar Switch Toolbar button: Allows to switch the toolbar which is splitted under very low resolutions (less than 460px). The button is only visible when the resolution is very low so that less than half the size of each toolbar button can be displayed.

3D isometric gameplay world

The OpenTTD world takes the form of a landscape, presented on isometric projection (strictly speaking rather dimetric projection) for that 3D look. You will spend most of your time playing here. The world is divided up into tiles, of which there are many types. Some are sloped, some are water, some are occupied by buildings, etc. This is where you build your transport empire!

The status bar

The status bar

The status bar can be found at the bottom of page, as can be seen in picture 1., and above in picture 3. It is divided into three sections.

  • On the left you can see the date. It progresses at about 1 day every 2.5 seconds.
  • The middle part, which takes up most of the space, shows various information:
    • The name of your company, initially "Unnamed". After you name your company it will show that name.
    • News messages pop up out of the status bar. Click on the status bar to display the last message.
    • If you have changed the message settings to "Summary" mode, messages will scroll by here instead of popping up.
    • If you have changed the message settings to "Off" mode, messages will be notified by a red dot.
    • It also shows if the game is paused by saying: "* * PAUSED * *"
    • While the game is saving, it will flash with "AUTOSAVE" if it's an autosave, then "* * SAVING GAME * *".
  • The right part shows how much money you have. You can change the currency in the game options window by pressing the "Options" button and then "Game options".

You may also hear "status bar" used to refer to the vehicle status bar.
