The difficulty with saying THE pulses passed
through each other arises with the energy. The
energy profile of the pulse arriving at the left
will look exactly like that of the one launched
from the right so it will seem that the energy
travelled all the way down the line for delivery
at the far end. And yet, from the experiment above,
when the pulses arriving from each end have the
same shape, no energy crosses the middle of the
line.

So it would seem that the energy that actually
crosses the middle during the collision is
exacly the amount of energy that is needed to
reconstruct the pulses on each side after the
collision.

If all the energy that is launched at one end
does not travel to the other end, then I am
not comfortable saying that THE pulse travelled
from one end to the other.

But I have no problem saying that the system
behaves AS IF the pulses travelled from one
end to the other.

Yet it sounds like you are saying that despite this charge repulsion and bouncing of waves off each other, each wave appears to be completely unaltered by the other? It seems to me that surely we would detect some trace of this profound effect.

. . .

Is there any test you can conceive of which would produce different measurable results if the pulses were repelling and bouncing off each other or just passing by without noticing the other?

There are equations describing system behavior on the assumption of no wave interaction, and these equations accurately predict all measurable aspects of line behavior without exception. Have you developed equations based on this charge interaction which predict line behavior with equal accuracy and universal applicability?
