The author outlines a radical urban plan built as long linear cities aligned with rail arteries, combining stacked electrified train lines beneath two stories of continuous housing and workspaces, roof promenades, and gardens. He details technical features such as poured-concrete dwellings, smokeless high-speed transit, integrated parcel and telecommunication services, and mechanized domestic labor, and argues these will eliminate slums, reduce costs, improve health, and simplify distribution by cutting out middlemen. The book blends technical description, economic argument, endorsements and a personal account of the inventor’s efforts, and concludes with a call to implement the design as a practical path to social and civic reform.
