Hey, so this map was made for that contest thingy, I think the title is pretty self-explanatory however just for the sake of explaining, this is the Inter-dimensional Railway Transit. As you can see it's clearly a big portal otherwise known as the Transflumer of the destinating conveyance. However, It's all a matter of perspective.

This was a collaboration between me, and TrialnError, where I made the terrain, and rendered it, and he made the structure and took the screenshots. I hope you like! ;-)

Here's the renders in HD resolution.
