An Innovative Solution for a Sustainable Urban Mobility: Tram Wave, The Ansaldo STS Catenary-Free Proposal Alberto Castagnoli Ansaldo STS Business Development Transportation Solutions BU
The Challenge Today several Cities centres and suburban areas are affected by aesthetically and/or architecturally debatable overhead catenaries transportation systems
The Challenge Cities are also seriously affected by carbon generating vehicles.. Public vehicles always run along the same path of private cars.
The solution TramWave, a Catenary- Free system TramWave is the innovative Catenary-Free power supply system designed by Ansaldo STS that doesn t constraint urban vehicular and pedestrian circulation. The contact line is composed by consecutive modules. Each module is made by 50 cm long conductive steel plates (also called segments), that are insulated between each others and release energy only when the train boogies are over them A mandatory condition for the contact line to release power is the presence, on the segment, of the vehicle with the vehicle power collector released, that activate the line and pick up the current The steel plates in contact with the power collector, are the only one energized the rest of the contact line is not fed The safety of people and vehicles is always guaranteed

TramWave main Benefits for sustainable urban mobility Facilitate the city development with low carbon emission Make the urban context more liveable, removing the visual impact of overhead catenaries and poles from squares, buildings, monuments, historical areas, etc Easy installation of the ground-level power supply contact line between the tracks for both new and existing tramway systems Power transmission from contact line to vehicles without any interruption/charging times (for both traction and auxiliaries) The closing of the traction electric circuit doesn t foreseen the use of the tracks no more problems due to the effects of stray currents, preserving the underground utilities (water and gas pipelines, electricity network underground cables, etc ) and the rails from electrolysis effects less maintenance costs Possibility to have a mixed power-supply system, by mean having TramWave and traditional catenaries on the same tramway line (ex. TramWave in the historical centres and catenaries in the suburbs), moreover it s possible to feed with Tramwave rubber tired vehicles like busses Total absence of electromagnetic emissions inside and/or outside the vehicle. No need of on-board big and heavy storage energy systems
