Super Bell Subway

Super Bell Subway is the third course in the Bell Cup. The course is included with the Animal Crossing × Mario Kart 8 downloadable content in Mario Kart 8. The course is located in a subway station, going through both the station and the track. This track only plays a half of the music when racing on the course, and the other half plays only when watching a highlight reel.

Course layout
The track starts in the station with a U-Turn going to the left right after the start. The track leads into a large area with stairs leading down into the subway. Automatic barriers open to let the players through.

The subway has trains running along the tracks. Throughout the subway, raised platforms can be used to drive on the trains. At the end of the subway, the train track splits and has stairs that lead up back into the large area of the station with another set of stairs taking the players to last bend before the finish. After the U-Turn is a straightaway to the finish line. The track does not contain any anti-gravity sections.

Shortcuts

 * Throughout the underground sections of the course, a Mushroom or a Star can be used over gravel sections cutting off turns in the track.
 * At the final U-Turn going to the left, a shortcut can be performed through a grass patch next to the Golden Bell Fountain with a Mushroom or a Star.

Trivia

 * The map that appears at the starting line of the map is for the city that appears under N64 Rainbow Road, meaning this track takes place under it.
 * Additionally, text on the upper left hand corner of the map mentions Toad Harbor, Wii Moo Moo Meadows, and  Wii Wario's Gold Mine. Also, there are signs located around the metro that refer to destinations of other courses in the game, hinting that the station is connecting all the courses together.
 * Fittingly enough, the track makes a few references to the underground levels in Mario games:
 * This track's music contains pieces from the Underground theme, much like Piranha Plant Slide.
 * World 1-2 from Super Mario Bros is referenced by the graffiti found during the underground section.
 * The graffiti also references Bullet Bills, Warp Pipes, Koopa Troopas, and a Piranha Plant, which is located before the World 1-2 graffiti under the ramp. The graffiti near the World 1-2 graffiti references the Koopalings.
 * Like Sunshine Airport, this track features a P.A. voice in the background that can be heard faintly. The female intercom speaks German, including several grammar errors however, and says general things heard in a German train station.
