Description
242 Train Factories work with 2 Locomotives, 4 Rail Cars and then 2 more locomotives trains. These are the factories used in my megabases. Supply and pickup trains arrive in the middle (unless they are supplying liquids).
If it is an outpost with assemblers, then I use 1000 logistic bots in each. Otherwise the liquid outposts, only need 5 or so logistic bots to deliver train fuel about the outpost.
For a demonstration of the outposts, see either of my megabase series on YouTube - https://goo.gl/AgDAkn
