Usually, it's very complicated to program a real time strategy game from scratch. Notable examples like Lemmings or Starcraft are software projects with a large amount of codelines. A much easier approach for testing out a complex domain is a railway track. In the screenshot, 4 switches are shown and the amount of 3 locomotives can drive through the network at the same time. The user can adjust the speed of the vehicles and he can activate the switches.
Unfortunately, the current prototype has to be controlled manual by a human operator. This is no longer state of art. Which options are available to automate the task, so that the train passengers don't wait to long?
