Hello and thank you for this mod!

I have a question regarding the values to enter in the "braking force": i am trying to obtain the most realistic braking so i started by entering 0.1, and while it made braking less OP, it was still way too strong. I then tried 0.01 but it looks like the trains are now back to their original OP braking.

Can you explain how values affect the braking force (i guess 2 is twice the base value and 0.5 is half?) and what is the smallest value that can be used? Thanks!

I think breaking has a minimum of 0.1, but that's vanilla Factorio enforcing it, not my mod.
I would just mess around with the value until it works and feels good. I'm basically just shoving it into the train properties and hoping it works.
