You guys can still add this feature to the mod files, even if it's disabled for the main game
As I said, could be great for some possible late scenarios.
It is not possible to implement and
completely disable without some side effects.
All you could do is to add some additional code that does not allow
Railroads, Trains and Trainstation to be built.
But
A) You would still see Trains and Trainstations in Colopedia and Gameconcepts.
-> Could confuse the player.
B) Would need to implement additional checks in the DLL that do nothing else than to forbid these things.
-> I consider that very dirty coding.
C) If a Scenario or ModMod of RaR is to be built, the feature could simply be used then.
->
Path to the Throne for example will use this feature (with different graphics of course)

Summary:
I believe that a feature should either be integrated in a mod or not.
Making dirty hybrids only lowers quality and performance.
This feature is not a simply "Plugin", it will be deeply woven into the logic.
(I have decided to introduce Yield_Coal for example and AI will get more logic for this, too.)
Optimally this feature would be combined with feature Inventions, which currently simply does not exist yet.
But that alternative would also simply not fit into the timeline of RaR.
