Factorio choose station with least number of items

Factorio 0.13.16 allows you to control which station a train goes to using circuit networks. This is a circuit network that will find which station has the minimum number of items, and send the train there. A text explanation of how this all works can be seen at this reddit thread: https://www.reddit.com/r/factorio/comments/4y49lj/circuit_that_sends_train_to_station_with_least/ Edits: There are new layouts for both the first, as well as every other station so instead of 7 combinators they use 2 and 4 respectively. New layout for the first station : https://drive.google.com/file/d/0Bx5xYriD9ymVNUNWeU1TcFhZT2M/view New layout for all other stations : https://drive.google.com/file/d/0Bx5xYriD9ymVdnRhR1Nyb1JMM3c/view
