Whats your main idea: A Minecart railway system that travels from spawn to various hubs around the map!
Would everyone benefit for this: Easier to travel, particularly since /f home dumps people into unloaded chunks
How would you implement it: Suggest that th e Admin faction could buy plots of land (much like how the CP/CN rail bought land across canada) in which they (or a trusted volunteer on their behalf) will build a 2-way rail system to various hubs away from spawn, much like how smaller towns would have rail connections to large towns. These plots of land would be admin owned, and could have creatively designed little way-stops along the way
Keep it creative and logical to the goldrush theme!
