Can we get a few images to see the mod?
And maybe a bref break down on the different engins and controlers.

I have added an image to show how equipment affects trains.

oh thanks, pretty neat!
Do the engins stats stack with multiple?
I see you created a train grid, any plans on adding quality trains increase grid size? I don't know if that is possible because I Think quality is hard coded. However would be a great combo and make people want to build quality Trains.

Only one engine has an effect.
Train grid size increases with quality. That is the game's built-in behavior for all equipment grids.

oh great! thanks for the info!
