Installing some track today that had been in storage for several years so I broke out of storage my track cleaning car that uses both a liquid and a rotary wheel. Besides not clearing my turnouts it was not running and a examination showed that somehow cleaning solution had gotten into the motor in the past and the motor was shot. Looking at Aztec they have a car based on a 36 foot roundhouse model and another based on a 40 foot car. Now that 36 footer would probably fit the bill for my curvature. So my question does anyone have the Aztec products and what pros and cons if any?
