Product name: 

Overland power supply system for the Barcelona tramway connection

Description: 

The new dynamic ground power supply system (APS), installed in the extension of the Barcelona tram network, eliminates the use of catenary thanks to a third conductor rail on the track, which supplies electrical power by activating and deactivating itself as the tram goes throught.
