The resource “pull” system will severely limit large factories

If you’re here, I assume you know how the buildings request resources and “pull” them across rail lines instead of satisfactory where every building “pushes” their resources out to a belt automatically.

This is a great system for t1 rails. It’s ok for t2. It will be nearly worthless after that. The reason is that the rails have no intelligence they simply send everything down the shortest path by distance not duration. This will quickly back up your rails without careful planning.

If you build your factories the same way you would in satisfactory, you’ll never run into this problem. But if you have to do that, why bother with the pull system at all?

There really is no upside to the pull system except for laziness in simple factories.
