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.

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