Keep your railroad running at its best with these track cleaner locos. Mounted on a customized fuel tank where it's hard to see, the Stealth(TM) system can be used to clean tracks at any time. Four spring-loaded cleaning feet ride the rail tops, and each can be equipped with any combination of felt or abrasive disks. No liquids are needed so the track gets clean and stays clean. A variety of diesels are available, which can be run alone or with other engines, either in the lead or as a trailing unit.
