Quite right, Bruce.

But San Francisco runs their F line on Market Street with trolley bus overhead over the tram tracks and the trams running off the trolley bus hot wire. No problems as far as I know.

Once I was driving PCC cars there and mangled my back pole so I put it under the hook, put the front pole up and while I was doing that the rear pole sagged down and touched the metal roof. Goodbye overhead! Lost 50 yards of copper.

Great photo GWB Two pole trams running on TB overhead of course has a potential for disaster - put one pole on +ve, the other on -ve and just watch the fireworks. Remember there is no overload protection of the traction cable between the two poles. So you could easily melt the overhead or cause a fire in the tram roof. This is one reason why we don't have such a system at MOTAT. But I wonder if New Plymouth had any such accidents? You know - keen kids wanting to help by putting up the poles? The photo makes me shudder actually.
