Carrying

At the beginning only characters can deliver items from one place to another. Characters can carry only some amount of items but as they can level up this skills they can increase their carrying capacity.

As you progress through the game, you unlock belts, catapults, trains and item teleporters for delivering. Belts and catapults are very basic tools for delivering available in the Wooden age. In the Steel age you unlock harvestin, planting, cutting and picking trains with the single transport trains for delivering items.
