U.L.P. is a company on Sodor. It is unclear what the company does or what their initials actually stand for, but they do own some goods wagons used by the North Western Railway. These wagons are painted in the company's livery of pink and with their initials (U.L.P.) painted on the sides of the wagons in white. Their trucks have been seen carrying china clay.
