Chorus City was a city on SwitchCraft 2 which grew out of the GTech™ End Cube via gradual accretion of additional roads and buildings, hence the oddly constructed road network and lack of overall design. It was constructed in the Outer End.
Despite the lack of advance planning, construction was more centrally managed than Switch City: all roads were constructed and managed centrally, and built to the CCIM standard of 4-wide concrete with 1-wide glass borders, a significant improvement over Switch City's cobblestone and stone brick roads. Novel street signs held above roads running ChorOS, a custom build of PotatOS Tau, were also used. At the time of its construction, only Keansia had similar concrete roads.
An AutoRouted Rail deployment was considered but never constructed due to lack of applications.
