Flatbeds and wellwagons are used for transporting large items such as cars, tractors, heavy machinery, and engines. One carried the rock crusher to the quarry, another took Caroline to the Elsbridge cricket field after she broke down, and another carried the Queen of Sodor. Most recently, Toby took Rheneas to Misty Island on a wellwagon, Thomas brought Kevin to the Docks on a flatbed to help Cranky, and Harvey had an accident while pulling some flatbeds on Gordon's Hill.
