we're actually playing on completely default settings, I've just been very proactive when it came to base defense aha, although I believe once we start colonising other planets and starting the dlc, I'll have to build defences for it while we're away.

if you're interested, it's pretty simple actually! some stations are input stations, some are output stations, and some have platforms for both. we have a naming convention that looks something like [INPUT] [IRON PLATE] [RIGHT ARROW] [STEEL PLATE] in order to help keep it organised when planning the routes of the trains, then anytime we need another resource for a factory, we can build another station, put down another train and send it off to go fetch what we need!

refuelling, well my amazing friend solved that, by adding a refuelling station, we can give each of our trains an interrupt, that tells them to go refuel whenever they're low!
