Siemens offers infrastructures and intelligent power-management solutions that allow towns and cities to reduce their environmental footprint and to improve quality of life for their residents. Among the broad Siemens' transportation portfolio, our APM solutions - first implemented in France in 1983 and now in operation on 12 different airport or urban mass transit lines worldwide - bring significant contribution to energy savings. Thanks to our Val, Cityval and Airval systems, we provide mass transit operators and authorities, as well as airport infrastructure managers with efficient, proven and eco-friendly transportation solutions. The purpose of this paper is first to explain the energy consumption chain for an APM. It includes a presentation of the solutions we have integrated in our product lines, Airval and Cityval (Siemens' state-of-art APM solutions resulting of the Neoval R&D program): system operation, vehicle performance and components. Second, we will present solutions successfully implemented by Siemens to optimize energy consumption on existing metro lines: coasting mode, as for instance designed for Paris metro line 14 with Siemens' CBTC and which results in an average energy saving of 16% ; and regulation of train dwell-time, which has been implemented on the 1st metro line of Torino operated with a Val 208 APM system with a saving of 3 300 MWh per year.
