Isana Underground

The Isana Underground (Mirselec Isana Domogute Nasgai, literally Isana Underground Rail) is one of the largest, most extensive, and most used underground train stations in the world. Covering most of the Risevan capital of Isana, it is also connected at several stations to the Bresnga Underground, as well as the national high-speed rail systems.

The Underground in its modern form comprises a total of 15 lines, of which 13 are "Trunk Lines" stretching from one end of the city to another, while 2 - the Gardaus Ring Line and the Outer Ring Line - are ring lines that connect with most of the other lines and encircle the city. The Underground is a key part of transport within the city, and is correspondingly important within city culture and society.

Description of the Underground

Despite being called the Underground, the IDN in fact runs both on, above, and below the surface; whereas surface rails and the occasional raised rails on pylons are used for the outer districts, the busiest stations in the city centre and along the border with Bresnga are underground, in order to conserve surface space and to merge in better with the Bresnga system (which is indeed completely underground).

Notes

Station Art

While the post-war lines of the Underground were built in a highly utilitarian, and sometimes even minimalist style, the lines in the east of the city, which are the oldest lines in the city, were richly built and decorated.
