Advances in energy efficiency of trains for New South Wales

Governments worldwide are recovering from the global economic crisis and returning their focus back to the environment and energy efficiency. Downer EDI Rail (DEDIR) has designed, and is constructing new Waratah 8-car double deck train sets for NSW under a Public Private Partnership. These trains have a number of class leading features, and potential for even greater energy efficiency, whilst delivering a level of lighting, comfort and information technology for customers and client. The design targets the three leading energy-consuming systems: Traction, Climate Control and Saloon lighting, and focuses on reduced direct energy consumption, increased energy recovery and mass reduction, which affects both energy use and vehicle performance. Significant energy savings have been achieved in comparison to recent RailCorp rolling stock fleets, with energy recovery, from regenerative braking at potentially 75% to 100% better than the post 1980s double deck fleets. Energy consumption in a simple area such as lighting will potentially save in the order of 1500 MWh per year for the Waratah fleet over the standard fluorescent solution. It appears that further saving can be squeezed from some smart control of lighting and climate control but will require client actve participation to achieve.
