This is the wiki for Simutrans Extended (formerly known as Simutrans Experimental). Simutrans Extended is not the same game with additional features, but a branch project which differs in several fundamental game mechanics from standard Simutrans.
Simutrans-Extended has been developed to provide additional features not found in Simutrans-Standard, and also to modify some existing features to change the overall balance of the game. The emphasis is on economic and operational realism, improving the gameplay balance, increasing variety, and making the game more challenging in the later stages (where, in Simutrans-Standard, it can be very easy), and less challenging in the earlier stage (where, in Simutrans-Standard, it can be very hard): in other words, to have a longer, smoother learning curve.
Simutrans Extended was (and still is) developed by James Petts, who, in a previous incarnation, used to pull long freight trains through the Midlands, day or night, and in bad weather. He still retains some of these character traits.
This wiki is, as usual, a work in progress. At the moment is is not intended to be a complete game manual. If you're a beginner, please refer to either the standard Simutrans wiki or the Simutrans Extended in-game help system to learn the basics. What you'll find here is more detailed explanations for the mechanics that are unique to Simutrans Extended.
Or download the latest nightly build, as a complete package with Pak128Britain.Ex (look for Simutrans-Extended-Complete.zip). Be advised that the latest version may always contain bugs. Switch on Autosave in the config file!
