Hyperloop Transportation Technologies says it plans to start construction on a 5-mile hyperloop test track north of Los Angeles next year. The company has partnered with engineering-design firm Aecom, vacuum system company Oerlikon and architecture firm Hodgetts & Fung. Hyperloop Transportation Technologies will soon select a builder for the project. Entrepreneur Elon Musk originated the idea of a hyperloop system, a vacuum-sealed tube that can transport people at speeds up to 800 mph.
