  • 1. About us: Finmeccanica An Innovative Solution for the Urban Mobility: TramWave, the AnsaldoSTS catenary-free solution Paolo Marino Finmeccanica is Italy’s leading manufacturer in the high technology sector. Business Analysis and Development Finmeccanica is the largest shareholder in Ansaldo STS with a 40% stake. 1
  • 2. The challenge… Today several Cities centres and suburban areas are affected by aesthetically and/or architecturally debatable overhead catenaries transportation systems… 2
  • 3. The Challenge… 3
  • 4. The solution… TramWave, a Catenary-free system 4
  • 5. TramWave ground-level line module Steel plate Binder Concrete #2 Concrete Module Negative Feeder Safety Negative Feder Internal contact connected to the Positive feeder Internal contact connected to Safety Negative feeder Positive Feeder 5
  • 6. Operating Principle Power Collector When the bogie pantograph is retracted in rest position: …the power collector in the upper position is unable to activate the power line segments; the pulling force is not enough to lift up the belt The vehicle can run over the line in coasting without activating the segments All the segments are not energized and connected to ground 6
  • 7. Operating Principle Power Collector When the bogie pantograph is released: …the power collector is in contact with the segments and its magnetic force attracts the flexible ferromagnetic belt, that push up the internal movable conductive contacts, allowing the closing of the electric circuit and the power transmission from the segments, in contact with the collector, to the vehicle 7
  • 8. Operating Principle Groud-level module’s steel contact plate Veichle body Train boogie power collector The steel plates in contact with the power collector are the only one energized 8
  • 9. Operating Principle ~ 50 cm 9
  • 10. Operating Principle ~ 100 cm 10

  • 12. TramWave: main benefits for sustainable urban mobility • Make the urban context more liveable, removing the visual impact of overhead catenaries and poles from squares, buildings, monuments, historical areas, etc… • Continuous power transmission from contact line to vehicles without any interruption/charging times (for both traction and auxiliaries) • No need of on-board big and heavy storage energy systems (supercapacitors) • No need of electronic devices or induction systems • The closing of the traction electric circuit doesn’t foreseen the use of the tracks  no more problem 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 • Regenerative Breaking and energy saving 12
