The single phase current is transformed from a fairly high voltage off the
feeders to 240V from the output of a center tapped transformer up on the
pole. With regard to that 240V, there is no neutral. The 240V comes from
the two secondaries of the transformer. And there is no + or -. This is
AC, not DC. It is 240V across the two poles.

It is 240VAC, but it is similar to differential signaling (each wire wioth
equal but opposite instaneous voltage & current) as in twisted pair
ethernet vs. AC with a ground reference as in coax TV cable (the ground
stays at a zero volt reference and the voltage on the center conductor
varies symetrically positive and negative in relation to the ground).
