After making my starter base, I was working on a train system using train limits, circuits, and bidirectional 3-8-3 trains. I realized the scale was too large for me, and I wanted something smaller and simpler. I had also messed up the fueling system, and wanted to redesign it.
I nuked the old system (literally and figuratively), and I want to switch to unidirectional 1-4 trains, but still using train limits and circuits to calculate the limits. I also want a single fueling (maybe adding multiple as the factory grows) station that is visited by all trains.
Any suggestions for planning or designing something like this? The only mega base I have ever made was a spaghetti mess and I’m trying to be a bit more organized in the creation of this one (the initial goal is 2.7k spm)
There is straightforward vanilla friendly mod from one of the Factorio developers that handles train refuelling and train depots, the Train Control Signals (you need to use vanilla station limit feature). Also aside of the already mentioned LTN you could try Project CyberSyn and/or TSM.
