RSDevTools

Kan det vara nått sånt här:

"For those wishing to take content creation to the next level, the developers of Rail Simulator are offering an additional suite of tools that enable professionals and experts to really get their hands dirty. The RSDevTools allow the creation and editing of the more complex elements of Rail Simulator, adding new content to the game and authoring scenarios, as well as providing more in-depth documentation about features, functions and facilities. However, you will need a high degree of specialist knowledge of railway systems, computer simulation and programming to use these tools effectively"
