Energy Storage System with UltraCaps on Board of Railway Vehicles 1 2 Dr. Michael Fröhlich, Markus Klohr, Prof Stanislaus Pagiela 1 Bombardier Transportation, Mannheim, Germany 2 Fachhochschule Amberg, Amberg, Germany Abstract The on board energy storage system with Ultracaps for railway vehicles presented in this paper seems to be a reliable technical solution with an enormous energy saving potential. Bombardier Transportation already made a lot of experiences in this field, e.g. equipped one bogie of a prototype LRV (light rail vehicle) for the public transportation operator RNV in Mannheim with a MITRAC Energy Saver. Outstanding feature was the daily operation of the energy storage unit in daily passenger service, and this over remarkable 4 years, since September 2003. With 4 years revenue service the new technology can be seen now as reliable. The very positive experience was the base for an order to equip several LRVs with MITRAC Energy Saver, which was just placed –the best confirmation of successful experience the customer RNV could make. The measured traction energy saving of approximately 30% confirmed fully the former calculations. The revenue service of the prototype LRV is stopped now to concentrate fully on the new order. Running the energy storage device on board of a tram brings additionally following benefits: • a dramatic reduction of the peak power demand, resulting on considerable benefits in the infrast
