It is efficient to use conveyor belts and pipes to transport goods from production buildings to storage units, while letting trucks balance inventory between them. This keeps truck utilization high, as they can always travel fully loaded. It also gives machines extra buffers, helping them operate without interruption.

For example, {0} can benefit by having {1} and {2} storage units attached via conveyor belts.

For storage you don't want to fill (such as {0}, pictured below), you can use the <b>{1}</b> slider to set a threshold. One that level is reached, vehicles will automatically remove the material and deliver it to another available unit.

You can also <b>set up alerts</b> to be notified if a storage unit becomes too full or too empty, which could prevent connected machines from working properly. This is especially helpful for critical resources like coal for power plants, where a shortage can disrupt power production.

Once machines are connected via belts or pipes and a first product is delivered / received, trucks will stop delivering or collecting that product from those machines. You can manually override this behavior using the {0} and {1} dropdowns in each machine's window.

Note that the red/green sliders have no effect on connected belts and pipes. For example, a storage unit set to <b>{0}</b> will continue to output products to belts or pipes.
