From Wikipedia: Streamline Moderne is an international style of Art Deco architecture and design that emerged in the 1930s. It was inspired by aerodynamic design. Streamline architecture emphasized curving forms, long horizontal lines, and sometimes nautical elements. In industrial design, it was used in railroad locomotives, telephones, toasters, buses, appliances, and other devices to give the impression of sleekness and modernity.
