Railroad construction is a major challenge for myself and many other Factorians. My ideal mod would be one that provides step-by-step instructions for building, putting, and repairing railroads.

I haven't used it myself, but this might help: https://mods.factorio.com/mod/FARL

However, I suggest you still learn how the rail system works first. You can probably still make a "bad" rail network with this mod, as I believe that you need to design the blueprints that FARL will put down.
