Stage 1: Received numerous aesthetic changes, including better textured buildings and spawn rooms.
Stage 2: Finishing up on final aesthetic changes (adding more destroyed buildings, rubble and crystals.) Still need to add more water.
Stage 3: Largely Untouched. The train has new carriages, of which some reflect the changes added to the "latest" version of Cactus Canyon (An empty railcar, gravel and rocket transportation were added, so less mobile classes could get to the other side while the train was in motion). No water at all here =P
