I am no expert on the GeoTrax trains but I do know that a lot of them are Push Along (not motorized) even though they take battery's for lights and sound like the 3 that I recently purchased for parts. However, the motorized ones do use that middle toothed rail for its movement as you can see from the 'Powered Car' that came in the Toy Story Exploding Bridge Set in the picture below.
