Abstract
Railenergy (Innovative Integrated Energy Efficiency Solutions for Railway Rolling Stock, Rail Infrastructure and Train Operation) is a European Commission sponsored project with the overall objective to increase the energy efficiency of the railway system thus contributing to the reduction of life cycle costs of railway operation and of CO_2 emission. The 27 project partners (railway manufacturers and operators, infrastructure managers, sub suppliers, universities, institutes and consultants) investigate, develop and validate solutions ranging from the introduction of innovative trackside and traction technologies, components and layouts to the development of rolling stock, operation and infrastructure management strategies.
