So water ladders, booster carts and boat elevators have now been broken in the 1.6 update - I need to find a quick way to get back to the surface after a long mining session!
Given that my shaft is 15x15 in size, what is the most efficient usage of tracks for a minecart system to transport me to the surface? I'm assuming that just running a track round the outside of this will be the most wasteful method, and that the fastest will be to make a tight spiral out of booster track (although this will be wasteful in terms of booster track needed).
What layout will give me the most speed / shortest travel time for the least amount of track used?
