Endless Mines With Kilometers of Minetracks, V-2

This is the same world seed as the one I downloaded before, but I built a bridge from the strange new spawn point, and have surveyed farther away too. I also have replaced most of my old boosters with gold power track, at least on two or three of the lines available. Return to main base from outposts by way of Portals, it's the only way, (except from the first base you get to from the spawn point, which you have a choice of minecart return or Portal).
