This underground rail system took me around 3 days to make from January the 5th (specifically for mining). The design originated exactly from an idea on Pinterest.

As of the awesome texture pack (True Realism HD), I will mention the materials by name.

•Spruce fences and slabs
•Stripped spruce logs
•Stone brick blocks and slabs
•Redstone
•Basic rails and powered rails
•Lanterns
•Basic stone and cobblestone (an extra feature behind the fences)

This little project was built without interacting with cheats (all survival)!
