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 the subway station which resembles the London Underground.

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. 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. At the final U-Turn going to the left, a shortcut can be performed through a grass patch with a Mushroom or a Star. After the U-Turn is a straightaway to the starting line. The track does not contain any anti-gravity sections.

Trivia

 * This track's music contains pieces from the Super Mario Bros. Underground theme, much like Piranha Plant Slide.
 * 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.
 * 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.
