Increases fuel consumption and decreases acceleration/braking to make trains feel more heavy and have a cost to running them.
Does not change the actual weight of trains.
The mod only changes the braking force, if the game's interaction with the locomotive doesn't apply it as expected, not sure what to do. Open to thoughts.
Let me know what options you're looking for and I can see how to incorporate them.
Perhaps what is happening is the train can decelerate faster if it is both braking and accelerating (in reverse) at the same time? If this causes the train to expend fuel, then I'd say it is balanced.
