Swiss Federal Railways’ (SBB) desire to reduce the energy consumption of its vehicle fleet has led to the development of a new lighter and more efficient onboard battery. Benedikt Vogel, on behalf of the Swiss Federal Office of Energy (SFOE), explores the intricacies of the SBB New Battery Technology project.
Despite rail’s overall high energy efficiency, the cost of power supply is still a major concern. Many initiatives are underway to reduce energy consumption, such as reducing vehicle mass and improving the energy efficiency of on-board systems says, Dirk Wimmer, general manager of SMA Railway Technology, Germany.
With recent advances in energy storage technology, urban rail operators are harnessing the ability to reduce traction power consumption. Venky Krishnan director of business development and special projects with Calbetux, United States and vice-president of corporate operations and communications, Kristen Frey, explain how flywheels offer a reliable and durable solution for wayside energy storage.
Japan's Railway Technical Research Institute (RTRI) is developing groups of railway simulators that create a realistic representation of the underlying operating environment in order to offer a comprehensive analysis of phenomena that are difficult to analyse using a single simulator, as Ikeda Mitsuru, director of RTRI's Railway Dynamics Division, explains.
In a time of scarce financial resources, metros are seeking to reduce operating costs by diversifying their revenue streams, adopting new technologies and embracing more flexible operating practices. Keith Barrow reports from Barcelona on how the city's metro operator TMB is generating efficiencies through innovation.
