Freight transport on the Rhaetian Railway plays an essential role in daily life, delivering food, beverages, mail, and other necessities across the rugged terrain of the Swiss Alps. Among the most recognizable and popular freight items are the COOP refrigerated containers, known for their variety of colourful designs, and the containers from Swiss Post (Swiss Post Ltd.), the national postal service. They are regularly transported in container freight trains or mixed passenger-freight formations, making their way through the scenic alpine routes of the Rhaetian Railway.
