Train Cars HO Scale Baby Ruth (2) Sizes (1) Track Cleaner

This is a group of two HO scale train box cars, One (the high cube) has a rotary sand paper holder inside to clean the tarnish off the your track, and makes a sort of chug chug sound going down the track.  This one marked "BABY RUTH GOOD CANDY" on both sides of the box cars, the other is a standard box car, marked "BABY RUTH GOOD CANDY", both are marked "TYCO" on the bottom. Both are in good+ used condition, no damage, very minor wear , some light dust in hard to get places, as seen in the pictures. The taller car with the sanding unit is 5.5" long overall x 2.25" tall and the other, is 5.5" long x 2.0" tall. As best I can tell, the track cleaning car is made that way from the factory. I have not seen one of these before, it actually works pretty good, a few time around the tarnish brass track, and I see a brighter difference. These two box cars are both vintage advertising cars from the 1970's era, sold as shown in the pictures with no original boxes. The price is for both.
