I also use "in" and "out", in combination with rich text. For example, iron ore stations might be:
[IRON ORE RICH TEXT] 1-4 Iron Ore - Out [IRON ORE RICH TEXT] 1-4 Iron Ore - In
Where the "Out" station is at the resource patch (ore comes out of the ground) and "In" is at the base (ore goes in to the factory). I also include the train type in my station names (1-4).
See https://lemmy.ml/comment/686775 for what I mean by rich text
Yeah I already have a book of tracks, but I will definitely add station blueprints to it!
