"An assembly plant is a building or complex of buildings where workers build goods from their component parts, which are created on-the-spot or in factories elsewhere. In many cases the goods are assembled using an "assembly line" style of production in which individual parts are added to the product by a number of workers, each of whom performs his or her actions in sequence as the product moves down the production line. The plant also may include a warehouse to store parts as well as the finished products.

Although a relative latecomer to the Industrial Revolution and manufacturing in general, by the early twentieth century the German plants were among the most efficient in the world. During the First and Second World Wars German plants built thousands of tanks, planes, and other war materiel under horrendous conditions and in the face of concentrated Allied bombing attacks. Into the twenty-first century the German manufactories remain among the world's best."


"Assembly Plants, the German replacements for Factories, increase a city's production at the cost of adding significant unhealthiness. Assembly Plants are required to build Coal, Hydro, or Nuclear Plants, which add additional production with the proper resources."

Difference from Factory

It can turn 4 Citizens into Engineer, instead of Factory's 2, and It can be built 50% Faster with Coal.
