With the upcoming 1.9 update, I thought I would share my small project.

My map consists of a a basic water shack, in a nice tucked away cove I found near my spawn.
And the start of my underwater/ground railway system, which only currently has a moon pool and a bit of a tunnel so far. All done legit, hence the project taking so long as clearing out areas for water takes far too long!

Shall possibly post underwater areas as a schematic eventually if enough people ask for them.
