Which returning Mario Kart Wii course appears in Mario Kart World?

Toad's Factory is the returning Mario Kart Wii course that appears in Mario Kart World.

Toad's Factory first appeared in Mario Kart Wii, where its industrial setting included conveyor belts, machinery and moving obstacles. Mario Kart World brings the course into its connected environment alongside original circuits and other returning tracks from the series.

The course is easy to confuse with other Mario Kart Wii favorites. Maple Treeway, Coconut Mall and Wario's Gold Mine also debuted in Wii, but they are different courses with different settings and layouts. Toad's Factory is specifically identified with its factory-themed industrial landscape.

Returning courses in World were reworked to fit the game's broader design. Some legacy tracks include changes in terrain, route flow and the transition between day and night, so knowing a course from its original appearance does not necessarily guarantee the same racing line in the newer game.
