Nostrian Subway

The Nostrian Subway System
also known as the "Nostrian Rail Network", "Nostrian Railway", or simply as "the Subway" is a transit system that serves the continent of Nostria.
Culture
Generally the nations of Chicken Island and the Bling tend to use the subway system more due to structures in their territories being spread further appart as well as there being a taboo around Nether Travel among many Bling subjects.
Lines
Red Line
The connection between Greenhill and the Northern Realm is the oldest connection of the subway and represents the formation of the modern Nostrian Subway System. The construction of the Southdine Station would later expand the red line.
Blue Line
The construction of the Blue Line, to Chicken Island, represented a milestone for deplomacy. Formally a closed off nation, the Chicken Island government decided to construct a train station going straight to Greenhill, which served as the first and only overworld connection to Greenhill until construction of the Feathershire Bridge two years later.
Pink Line
Originally the Pink Line was constructed as a private connection between Kisinja's castle and Chicken Island, the construction of this line was essential for Kisinja to be able to have her home in Feathershire while she could still be well connected to the capitol of her nation
