Radical Train

Radical Train is an action stage from Sonic the Hedgehog (2006). It appears to be a terminal station for Soleanna. It appears in each character's story at the same exact time with each character having their own intentions. Sonic's and Shadow's stages involve a race against a train to either save or destroy it (respectively).

Sonic
Sonic travels through here in order to rescue Elise. He has to stop the bombs to keep the trains safe and find Elise's train. When he reaches the train there is a mach speed section.

Silver
Silver travels through here to find Sonic so that he can destroy him for good.

Shadow
Shadow travels through here chasing Eggman, and manages to stop Silver destroying Sonic. He also rides his motorcycle to catch up with the train and has to destroy it.

Trivia

 * Radical Train and Aquatic Base are the only two levels to not appear in End of the World.
 * This level is not used in Tag mode.
 * The freight locomotives in this level are based off the American EMD SD70M, and the red passenger train is not based off a specific prototype, however it does bear a resemblance to generic European multiple-unit trains.
 * The music in this level seems to be a remix of Crisis City's "Tornado" music.
