Grind Rails are likewise more or less the length of a foot wide, and typically taller than they are wide. They are also extensively long, as per their design, stretching through the landscapes in the shape of either straight lines or flexible formations that go up, down, left and right. They typically float in the air (either on their own or via scaffolds), although some of them also lie close to the ground, like railway rails.

Grind Rails are usually either solid bars or tight cords. 2.17 Mario & Sonic at the Olympic Games Tokyo 2020.
