A Rail is an object in Kirby Air Ride which Kirby and other playable characters can ride by contacting one end of it. Rails are typically long and winding, and will force the rider to travel (usually at high speed) from one end of the other without the option of getting off early or turning around while on the rail. While on a rail, racers may only brake, boost, Quick Spin or use an Inhale, Copy Ability, or held item. Rails may also have boost sections on them, which function like Dash Panels.
While most rails are stationary, some - like the fork rail in Magma Flows - may move left and right.
The mine cart tracks in Celestial Valley act as rails.
