Gravel surface

I'd love a gravel surface. This would work really well for rail yards and industrial areas.

I don't your point; you can already dump gravel to make gravel paths and areas. Can you elaborate?

As in a surface like the concrete surface or cobble surface. This would be a huge quality of life improvement than ripping up a factory, digging down 1 level and dumping gravel.
I suspect it would be quite easy to implement too.

Asphalt! We do not have asphalt option whilst we are battelling with diesel byproducts and have tons of gravel.
We need and asphalt production line and an asphalt road option
Thanks, great game!

Yes, I would love to place gravel between train tracks. I know I can force it but having the option under surfaces would be amazing!
