Electric trains, but UPS-friendly. Provides battery-powered locomotives, reusable battery packs and charging facilities. Balanced for vanilla gameplay by default, but trains can be as fast as you want.
Mods introducing new content into the game.

There are already several recycling mods out there, so in the interest of balanced interoperability, perhaps a checkbox option to disable recycling?
Or alternatively just to boost difficulty.
There you go.
Awesome!
