'Logistic Train Network' (LTN) is a very popular mod for Factorio that lets your trains behave more intelligently. I've never used it because I had always thought that you could accomplish anything you wanted with the circuit mechanics included in the base game. All over reddit and discord I had seen people mentioning a desire to make 'Vanilla LTN', followed by other users telling them it was not possible. So I decided to give it a try!
I have no idea if this has been done before, because I didn't/don't like to look to other people's creations for inspiration or help. I'm kind of a masochist that likes to suffer through problems until I solve them myself. That being said, this is the product of around 150 hours of effort. I hope you enjoy it!
The song is Dvořák's Symphony no. 9 in e-minor.
Obviously I do not own the rights to the song, nor do I profit from its use in this video.
