Well.....this is the last of the mods to be worked on....still working on some ideas.

This module will have a continuous separate loop, allowing a small train to circle around it and not interfere with the main line.

I found this pic on one of the NTRAK sites, it gives me a few ideas.

As mod2 is connected to mod4 (the mountain and mine mod), it will fit in with the mountain areas, as the tracks will be elevated towards the front.

It will most likely have either a logging town, or something similar.
  Perhaps even a military base, who knows!
