Rail Canyon is the seventh stage of Sonic Heroes. The teams are mostly grinding on rails throughout the stage. There are special rails which can can be changed from blue to red, allowing you to take new paths. While grinding, players must be careful to avoid the trains, some of which are on the same grind rails as the one you're currently grinding.
