== Basic ==
'''Task''': you need to cross another belt, pipe, or any other entity; not more than 5 tiles.
 
* select underground belt and make sure, it is in the right direction (press R until it is)
* place the to entry-section
* the underground belt keeps selected but it has changed into the exit section
* place it in the direction of the entry, not too far away.
Note: Rotation key (R) can also be used to invert tunnel flow of placed underground belt.
 
== Advanced ==
=== Behavior ===
'''For a more founded introduction into the belt mechanics see [[Belt transport system]].'''
 
Underground belts can be used to cross different flows of items without interfering. They move items like a [[Transport belts|normal belt]].
[[File:Split-swap.png|thumb|256px|You can turn the order of the lanes or split the lanes completely with the underground belts trick]]
* You can cross any number of entities and all types of ground, like water, swamps, etc. (input and output of course over water)
* You can cross other underground stuff (any number of underground belts or underground pipes). They won't be mixed.
* For the connection only the endpoints (entry-side and exit-side) are relevant.
* The maximum distance underground is 5 [[tile]]s.
* An underground belt pair with a blocked output stores up to 20 items. (Per lane? Untested!)
* If you mine an underground belt, up to 20 items are recovered, the remaining items in the underground are placed into your inventory.
* The half of the underground belt tile with a belt can accept input from the side. The other half (with a tunnel entrance) blocks incoming items.
 
This last fact is important, because it can be used to do some tricks.
 
== Much more uses ==
 
* [[Underground belts/More uses]]
This explains in detail the splitting lanes trick. This is a very useful "misuse" of the underground-belt output. See right!
