Yup, the image isn’t loading for me, but this is the way. Establish blocks with uniform size, so you can simply stamp them down. The nice part about this is that you can easily create loops without needing to worry about whether or not the ends will meet up; Since they’re all the same size, it’s just making a big grid.
And yeah, 100% use two lanes. Train path finding is odd, and having two separate lanes for bidirectional travel is extremely important as your factory gets larger.
I usually incorporate power lines and logistic bot ports in the designs too, so that I don’t need to worry about running those separately. Space the grid out so it coincides with your logistics bot coverage. You just blueprint it out, and then your logistics automatically expands to cover it and build it out as soon as the roboports and power lines get placed.
Lastly, establishing a standardized train size will help with being able to stamp down train depots. If all of your trains are 2 engines and 8 cars, you can design your depots to account for that standard size. Then just include a spot for inputs or outputs (and a few places for waiting trains) and you’ll be golden.
For instance, I usually had four balanced blue conveyor belts of input for my pickup depot. Two train stations with the same name (so trains can pick whichever one is available) and two more spaces for waiting trains. So a single station can have up to four trains loading/waiting for pickup, and they’ll load as fast as the four blue belts will carry inputs. I simply tie my inputs into those balanced belts, and the blueprint handles the rest. Something like this, except I normally use two single-sided pickup stations instead of a single double-sided station:
Sorry for the image not loading, it seems like catbox stopped working for a while, these images should work.
This image shows my current setup for making yellow and purple science, it is not yet optimized because I’m still at gleba. My idea is just using rare or higher tier elements for making science,
I already use different blocks for different purposes, this image shows my science block right next to the station block,
Finally, the design limits my current maximum train size to two wagons, for my copper mine I use one line to load chests that then load into the train for maximum throughput as long as there is a sufficient delay between trains,
