Tile improvements are created by Workers on most terrain types. All improvements except Roads and Magrails can only be built on terrain owned by the player's colony.

A given tile may have only 1 tile improvement; any attempt to build another one on the same tile will result in the previous tile improvement being replaced.

Note that most tile improvements only improve the tile yield, and thus have effect only if the relevant tile is being worked by a Population Citizen from a nearby city. Strategic resource improvements, however, also add the number of the relevant strategic resource to your total (regardless of the tile being worked, or not), while transportation improvements work at all times.

Standard improvements[]

These improvements can be built anywhere there is suitable terrain.
