RailroadsOnline Extended

RailroadsOnline Extended provides an in-game minimap, with the ability to remotely control switches and locomotives. In addition, RROx allows you to teleport to various locations and trigger autosaves.

Antivirus warning

RROx needs to inject code into the game to function. However, this is not something regular programs do, and as such, it might get detected by your antivirus.

If necessary, you can add an exception to your antivirus for the following folder: C:\Program Files\RROx (This is the default installation directory. It can be changed during the installation).

All of the code is open-source, such that it can be verified by others to make sure it does not contain any malicious code. RROx attaches to the game using DLL injection. This means that no game files are modified on disk. By closing RROx and restarting the game, the game will run completely unaffected. To start using RROx, click the attach button below.

How to use

Watch the demo video that shows the basic usage of RROx (This video is outdated as it shows version 1. A new video for version 2 will be available soon). In addition, the Info tab gives more a more detailed explanation of how to use it.

Frequently Asked Questions

• Minimap not visible: Please make sure that the game is not running in Native Fullscreen-mode. Please switch to any other mode to get the minimap to work.
• Attaching works, but the map stays empty: Please make sure that you are not running RROx as administrator.
• The game screen is black: Disable hardware acceleration in the overlay settings and restart RROx.
