After many days, I'm proud to announce that I have successfully build a subway underneath Spawn City! There's a local shuttle that circumnavigates SC in both directions, as well as an express line that goes from one side to the other. I have plans to extend the express line to go outside of Spawn city and into the wilderness a bit, but that's a huge project for another day.

Bring your minecarts, and ride around for a while! Enjoy the fruits of my labor, as this is probably the biggest project I've ever done on this server, and the biggest project I've done in survival in many years.

All the screenshots provided are from the local shuttle tracks.
