Why I am so grateful for maps in my serious-survival-save.
First pic: Planned things. Blue circle is going to be like a library and astronomy tower island. Green circle is current base of operations, residence, farm, etc. Red circle is proposed new walled coastal village. Orange lines are where I literally dug out the connections between my island and the other continent because I wanted to at one point make a wall all around the island but decided against it. Yellow line is planned rail lines unless I feel like installing Flan's vehicle mods (in which I'll just make roads).
And yes, three stacks of planks because I was gathering materials to make the rail stations. I only use stone tools because they're easy to make, I'm only using my iron for precious ores and armor, and eventually rails. I have like 2 gold (spent 4 to make the watch which is always needed), and only 2 diamond.
