Hi, I'm THEliberator03, this last 4 years I've been working slowly in this map, it is in a very early stage as I have lost 2 times previous versions but I'm still working on it.
Some info about:
--Trying to be the most realistic possible:
----Based on a schematic map, the real map is too complex for a minecraft representation.
----Most decorations are based in real life info, photos, maps, etc.

I'll be updating the map with every new station/tunnel is built
Current status: Working on the map again, finishing the version 0.1.03 (v.0.1.03_beta is uploaded, that means BarĂ³ de Viver is not finished yet)
An updatet map of the underground system and parts under construction (or that are planned to be constructed):
A modified version of what I've done (delighted in dark blue):
