Rail Canyon

This a rather Tedious level and is also the level with the most grinding. The level starts with speed. Sonic/Shadow/Espio/Amy in the middle.Fliers on left and power on right. You can rake up a bunch of Rings just on the rails so look ahead! proceed to the blue rail but remember while in midair to switch to the formation you want to level! (I always do flying). there should be some robots around some barrels. Go left around the Egg-bots (as I've nicknamed them)to find the gold key. Remember, DO NOT GET HIT WITH THE GOLD KEY!IT'S A HAZARD TO YOUR PATIENCE!SO destroy the Egg-Bots first.Also if you're a showoff and bored go rail jumping,yes rail jumping and only as Speed formation.
