been posted before, im sure. my idea would be a raft basically with iron wheel. to make this one must attach iron ribbons to a regular wheel. and attach to a cart/raft. the tracks could be placed anywhere and made by 2 iron tracks and 3-4 logs, for mines it would be slower than outdoors unless floor is reinforced. the cart would would work like a upgraded sail boat, 3 large crates or 5 small crates. being able to push 1 tile and a heave to push so many tiles based on body strength. with someone who delivers could have multi carts lined up ready to be heaved into the warehouse. while your mining, loading ur cart and heaving it to the forge to get smelted to then be carried out and sorted. ideas? thought? would it fit in wurm today?
