LTN - Logistic Train Network

by Optera

Adds logistic-train-stops acting as anchor points for building a fully automated, train logistic network. It can handle all possible train configuration. Just send all trains to depots and LTN will pick the best suitable train for a job. LTN cuts the amount of rolling stock required to run a megabase down to 30% or less. With cargo ships installed also adds a logistic port for ships.
