Trade route (Civ5)

== Vanilla Civilization V and Gods & Kings Trade Routes ==
A Trade Route is a link formed between a civilization's cities and its , which traders regularly use to move and conduct their trading. This might happen via land, using s, railroads, or via sea, using s. A Trade Route is open with a city if one of the above-mentioned infrastructures is in place at the beginning of your turn.
 Trade Routes can be formed even if the connection is not direct. For example, if the has established a connection to City A via a , and City A is connected to City B using s, then both cities are connected to the . As long as there is a transport chain ending in the , a Trade Route is opened and functional.
Note that for the to be accessible by sea, it needs either a built in it, or it needs a road/railroad connection to another city with a . So, for example, a connection won't be formed if the peripheral cities have s, but the itself has no sea access.
If an enemy pillages a road or uses ships to blockade a coastal city and there are no other connections to the , the Trade Routes will be lost until the roads are repaired or the ships leave or are destroyed.
Once formed, Trade Routes earn certain amount of for the civilization. Every tile with a road or railroad costs per turn, meaning not all Trade Routes are necessarily profitable. The output for any Trade Route between a and a city is:
Gold\_output = (City\_population \times 1.1) + (Capital\_population \times 0.15) - 1
For example, with a of 6 s, a city with 4 s produces 4.3 per turn, while a city with 5 s produces 5.4 per turn.
Building Machu Picchu increases by 25% from each Trade Route. Prior to Brave New World, Arabia increases the output of each Trade Route by 1.

In this expansion pack, trading has been redefined by introducing a new type of trade routes:  routes. Traditional trade routes between your own cities still exist, but have been renamed City Connections, and function the same way as before. We can also think of them now as "Domestic Trading," done automatically as soon as you establish an infrastructural connection between a city and your .
The new type of trade routes may be labeled "" and are established manually - not only within your own civilization, but also with other civilizations or even s. Since in Brave New World production from terrain is significantly reduced, the new trade routes become vital for maintaining your finances. Because of the complexity of the new system, it enjoys a separate article.
