Any Trains with Brushless Motors please ?

Well I so far am only aware of Tomy, Tomica and Plarail trains with commutator ( brushed) type engines/motors that spark to reverse polarity to turn the motors and create a spark as they do so.

They give off that burney type smell ( ozone ) Best Mark

None of my trains do that, or have any burning smells...

I'm only 13, and have never heard of commutators or anything about reverse polarity or sparking in the motors.
As far as I know, the motors of the locomotives are connected to battery terminals by soldered metal pieces, and the motor turns a gear, which turns a whole bunch of other gears, which further turn the gear fixed onto the back wheels' axle.
