Misty Island Zip-Line (also known as Misty Island Zip-Line Set) is a Collectible Railway and Adventures set. It features a zip-line destination containing Ol' Wheezy who can load Thomas' red cargo car with wood underneath. Thomas can then go round the figure 8 track layout up the brown and green slope to the top where he can travel down the zip-line to the lumber yard. The wood can then go through the spinning sawmill piece. The Collectible Railway version uses its yellow track system, and the Adventures version uses its grey track system.
