No, the pantographs supply traction power to AFAIK one 25hp formerly 3-phase Motor.
Traction really is by adhesion.
Now the trick is that they use the cable to balance the weight of the two cars ( one up, one down ), so the actual tractive force need not be that high.
Correction: The power of all trams is 600V DC now.
Seems that they use the second wire as the return line instead of the rails.

I know people like that. They just aren't happy until they get something so complicated that even they can't understand it anymore.

They also changed gauge !!
The Lisbon system started out as Standard Gauge, then swapped to NG !!
Looks like Helmut finally got it sorted out !
