Reply to "Why is AC Voltage applied to the 3 Rail Track while the Locomotive motors are DC Voltage Motors ?"

For the record, all electronic based systems function on DC.

Well... not really.  While it's true that there is DC used on these boards as well, there are still AC command boards and conventional boards around, the ERR AC Commander for instance.   It uses triacs to directly switch the AC for the AC motor.  Lionel also has the ACDR board that serves a similar function.
