So if I'm understanding this correctly (and I'm probably not!) the circuitry for the motor (in this case it is a Dallee unit) reads the incoming current differently than from the (more or less) "direct" line from the track to the smoke unit...?

More or less. The modern transformer supplies a higher voltage at all times which gives the Dallee unit more power to draw from. You can think of the difference in modern and old transformers something like driving a car. the old transformers work by adjusting how far you press the gas pedal and holding it at your desired speed. the new ones work by pushing the gas pedal all the way to the floor or taking your foot completely off, really fast.
