Having a rail system in grounded 2 will make transporting materials across map and up hill easier. The rails can be made of pine and rust and spider silk. It would be a Huge impact to the game and building.

I do already have bridges built all over the map so being able to lay down tracks on those does sound appealing. (Even if I had to upgrade all the surfaces to stems or better first. Grass flooring just feels flimsy when I think about it for a railroad.)

Zip lines are coming so perhaps a cable car if tracks are out of the question. .
