Tankers, also known as Wagons, are round, cylindrical wagons designed for transporting liquids and other gaseous commodities.
Sugar tankers are used for transporting sugar. They appear in the book Dustin Comes in First.
These tankers are based on standard 14 ton pre-war tankers common across most of regions.
The sugar tankers are painted sky blue. They have the words "SODOR SUGAR" and an image of a sugar bag painted on the front and rear ends.
