The AutoRail was created and maintained by DocJade and DrCats
This is a mere modification to that to update how train requests functioned as I found that I would get dozens of trains with the same item idling in depots. This is not a perfect solution but it is what I made for myself. It requires a bit more work on the users end. Reminder to connect your wires!
