Disclaimer: I've cheated.
Ever since I've reached the map limit and my computer's limit in Transport Tycoon I've wanted to build something like this. The problem was with previous versions of Factorio I reached unbearable UPS limits quite quickly, but the general gist of things was always to have a massive railway network to transport goods as needed between large factories. Each module in the end makes 5k of each science, I wanted to go for a 20k SPM base. Also, I usually liked to play together with the landscape, like this:
You can find the savegame (181.41 MB) here https://depositfiles.com/files/n1au1qurm to check it out and take a tour of the factory on the PAX train which should be waiting at the spawn point.
