SBB – on track towards energy efficiency
31 January 2017 • Author(s): Oliver Johner, Head of SBB’s Energy Saving Programme
Travelling by train uses four times less energy than driving a car and utilises 90% hydropower too. Swiss Federal Railways AG (SBB) already makes a major contribution to sustainable mobility – and will continue to do so in the future. However, it also remains the largest consumer of electricity in Switzerland and, due to the ongoing expansion of services, still more traction power will ultimately be needed. This article, from Oliver Johner, Head of SBB’s Energy Saving Programme, addresses the ambitious plans of the Swiss rail company to achieve greater energy efficiency.
SBB is aiming to save 20% of its anticipated annual energy consumption for 2025, equivalent to 600 gigawatt hours. For this purpose SBB has implemented a comprehensive energy saving programme. Adaptive control (ADL) holds great savings potential. This software calculates an energy-optimised driving profile for all trains that also has a positive effect on timetable stability and punctuality.
