Propulsion Systems for New Generation Trolley Buses Why electrical traction?
� No energy loss at a standstill (e.g. at traffic lights)
� Electrical Motor = Electrical Generator� Energy recovery when braking (start stop / downhill)
� Excellent acceleration (maximum momentum from standstill)
� High efficiency � Minimum of energy consumption
� Lowest possible noise level
� No exhaust / CO2 / particle emissions at the site
� Highest level of environmental friendly transport technology

Propulsion Systems for New Generation Trolley Buses Why Trolley Bus?
� Excellent climbing characteristics
� Little vibration
� Clean, safe and popular
� Makes cities more livable
� Higher ridership -> improved income
� The recovery of braking energy � savings of up to 25%
Overhead wire advantages:
� „Rails in the sky“ gives constant visual presence in public areas
� Accessibility by public transport systems more obvious and noticeable
� Fewer accidents
