D20.2: Improved aerodynamic, development & demonstration intermediate report n°2
The FP4-Rail4EARTH project aims to improve the sustainability performance of Europe’s railway system and contributes to the objective of a climate-neutral Europe by 2050. Within this framework, Work Package 20 focuses on improving the aerodynamic performance of regional trains. The activities aim to develop accurate numerical methods to predict the aerodynamic behaviour of trains and to better understand how specific components influence aerodynamic loads and energy consumption. The work combines advanced computational simulations with experimental testing in wind tunnel facilities. Researchers are analysing airflow behaviour around a generic regional train model to refine and validate predictive methods. In parallel, the influence of roof components and pantographs on aerodynamic drag is being investigated. Various roof configurations are being tested experimentally and numerically to identify solutions that reduce drag and improve train efficiency. In addition, a modular full-scale pantograph model has been designed and tested to study its aerodynamic behaviour and optimise the interaction with overhead power lines. These investigations support the development of improved designs that reduce drag, enhance power transfer efficiency, and minimise wear of components.
How it brings us closer to achieving better rail for Europe: By improving the aerodynamic design of trains and key components such as roof equipment and pantographs, this work contributes to reducing energy consumption, operational costs, and CO₂ emissions in railway operations.
