ok cool, thanks for replying.

It is only aesthetic, the only thing that can be customized is the power and weight to accelerate the train faster. The mod is mainly based on the Miami MetroMover.

Hi, my understanding of rubber tire transit systems, like the Paris Metro, is that they were adopted because allows more throughput than rail by providing better acceleration than metal-on-metal. I'm wondering if this mod is an aesthetic change, or if statistics of the livery show these characteristics?

Hi blakegarner54, look for the "Concrete runway trains" research to unlock the entire infrastructure for rubber-tire trains. The trains are electric and before using them you must have unlocked research "Rails II". Surely you have the mod activated, but if it had not been activated, you can activate it without problems by loading the game in the menu with three dots.
I hope I have solved your problem.

I can't build anything from this mod and there is no "Rubber tire railway" in the research menu. What can i do?

blakegarner54, What is the problem you have with the mod? It requires having the electrified tracks unblocked for the trains to run.

Doesn't do anything
