Track

Tracks are new objects found in Super Mario Maker. They can be produced in eight directions, and can be made into one-way paths when connected to each other as is, or loops when connected back to the start. If the player places an object on a track, it will move along the set path. The direction in which the object moves initially can also be set. On a non-looped path, once an object reaches the end, it will go back the other way; However, tapping on one of the two endpoints will make it disappear, causing any objects that reach the end to fall off the track instead. If the player shakes a track, it will make it rounded. Doors and large-scale objects such as platforms and Warp Pipes cannot be placed on tracks.

Objects placed on tracks almost never interact with untracked objects, with the exception of Mario. For example, if a block or P-Switch that was placed on a track derails off of it, it won't collide with any outside object, but fall through them instead.
