I wish you would have given some concrete examples as I was curious what experiments are possible with your code in OpenTTD.

There was only one I could find: "exploring the performance of trAIns". I looked at the "trAIns" link and cannot understand what it does, other than being GPL licensed.

It's all very cryptic, without any explanations. To me that stands for "if you don't know already, you need not apply". Too bad.
