3rd trolley:motion Conference 2012
Following previous events in Zürich and Luzern, trolley:motion have now chosen Leipzig as their location. Re-introduction of trolleybuses has been under consideration in Leipzig over the last three years; the recent introduction of hybrid buses has been a first step towards electric road-based public transport. The outcomes of the EU project TROLLEY have been integrated into the conference. In addition, the “euregia 2012” will take place in the Leipzig exhibition grounds as well as a newly established expert forum “new mobility”, which deals with future mobility using networked city and regional infrastructure.
For road-based public transportation, electric mobility represents an ever increasing challenge. Traditional trolleybus systems must continue to develop in innovative ways, in order to bring their well-established advantages into full effect. Future systems for electric bus traction are nearing technological maturity, thanks to focused R&D and effective support programs. Now it is essential to complete the developmental process and then test these innovations in everyday use. Verifying the utility of such new systems in a technologically transparent manner will help ensure success. The project "EU-Trolley", which has been supported by the European Union, directly contributes to these goals. By hosting this conference in Germany, the actual ,mother country" of electric bus technology, we hope to provide an impetus for bright new ideas and to move forward the development and application of future-proof solutions.

The new Hess Lightram will be on display during European Trolleybus Day on 22 September 2012.
ETD is a public-oriented event organised every year on the first Saturday of the European Mobility Week. The event is generally accompanied by information activities, contests, games and education around various aspects of trolleybuses. Target groups are all passengers and potential future passengers.
The European Trolleybus Day is a highly targeted event marketing tool to promote trolleybuses as clean and sustainable urban transport mode established by the European project TROLLEY. download brochure
Esslingen, Eberswalde and Solingen sign the “Declaration for Electric Trolleybus Mobility”
Dr. Jürgen Zieger (Mayor von Esslingen), Gunter Mackinger (Transportation Director of Salzburg AG), Frank Wruck (Managing Director of Barnimer Busgesellschaft), Mickaél Pandion (Managing Director of Städtischer Verkehrsbetrieb Esslingen) & Conrad Troullier (Stadtwerke Solingen GmbH – Verkehrsbetrieb)
Salzburg, 4 July 2012, Working together to promote trolleybus systems.
The declaration underlines the determination of the three partner cities to work together in promoting trolleybus systems as environmentally friendly modes of public transportation and generally advancing the use of electric mobility in urban areas. Gunter Mackinger, Managing Director of Salzburger Lokalbahnen (SLB) and Lead Partner of the TROLLEY Project, served as moderator for the signing ceremony.
With its 100-year old tradition of electric urban mobility, Esslingen am Neckar is a model example of how a city can maintain a historically-rooted trolleybus network and at the same time deliver innovative, future-proof urban mobility that is completely emission free.
At the expert colloquium on electric mobility, leaders from science and industry gathered to discuss the latest developments in electric public transportation. The participants were in agreement that utilizing the potential synergies of different transportation sub-systems was more important for the future, than focusing on a culture of competition.

About 100 participants attended the congress, which took place under the patronage of the Transport Minister, Winfried Hermann. Representatives of manufacturers, operators, the worlds of research and politics as well as groupings offered new developments, ways to and opportunities for electric bus transport. Mickaél Pandion, the work leader of the Esslingen municipal transport operator, presented a cost comparison between battery- , hybrid- , and trolleybuses. The trolleybus is only 2% more expensive in operating costs, while the hybrid bus is 25% more expensive to operate. No accurate figures are yet available for battery buses because there is no series production yet. The infrastucture costs for diesel buses in Esslingen are 0.14 Euro/km, while for the trolleybus these are 0.46 Euro/km including overhead mainainance. Optimising both staff costs and depreciation charges would reduce this to 0.26 Euro/km, thus only 0.10 Euro/km more than the diesel bus.
There were further presentations about the strategies of Esslingen and the land of Baden-Württemberg. Christian Soffel, project engineer of Verkehrs-Consult Dresden-Berlin, presented Dresden's "Trolley Plus" as a way forward. Unlike the earlier Esslingen DUO-busses, a vehicle from the "Trolley Plus" project would posses a high power energy store. This energy store would be charged by recovery of the braking energy, while recharging would also be possible during journeys under the overhead. In this way overhead would only be required on parts of any route extensions. The operation of routes 113 and 118 were cited as a model, and the district of Berkheim should be served from Zollberg without any overhead, using the battery store. Partial electrification of other routes would then come under consideration, for example trolleybuses on route 109, which has a 15 minute frequency, would only need a single track overhead in the uphill direction. Operation on the level would be from the energy store, which would be recharged in the downhill direction because of the frequent braking.
International experience from Switzerland, Rosta Rica and the Czech Republic was also presented. Arno Kerkhof, Senior Manager from UITP, drew up a balance sheet of world wide experience in trolleybus operation. Professor Ernst Pucher from the Institute of Vehicle Propulsion and Automotive Engineering at the Technical Universty of Vienna presented the "Primove Road" project, which uses power induction. A field trial with buses was being run in Mannheim by Bombardier, so these were absent from the conference.
The presentation from André Eichhorn, Area Sales Manager of Kummler + Matter AG, Zürich on the "Integration of Infrastructure into the Townscape" covered the regrettable general opposition to the installation of overhead wiring. In contrast Dr. Messerschmidt of DIaLOGIKa GmbH presented his project study on rewiring in motion using a computer programme.
During the congress 14 buses from 12 manufacturers were exhibited. The juxtaposition enabled a comparison of systems. The exhibits comprised hybrid buses from Daimler-Benz/ Evobus, MAN, Irisbus, Volvo and Hess and trolleybuses from Solaris, Van Hool and Hess as well as pure battery buses from Contrac, Rampini und SOR.
