Fold Up Thomas Storage Box is a Plarail item. It is a storage tub which features Tidmouth Sheds as its lid. The sheds can be expanded and fitted with the included Y-piece of track. The engines can leave the shed when their stall's lever is flicked. The tub can also be tipped upside down and become a double track support, the same size as three Rail Girders. The tub can be stored with engines inside the shed and their rolling stock in the bucket.
