The Kato Concrete Illuminated Bumper Track operates off of track power and requires zero wiring - just attach to the end of your spur and it′s ready to go. This bumper is ideal for modelers who are operating stub-end spur tracks and switching yards and want to be able to tell at a glance if a track is live or not. The Concrete Illuminated Bumper Track is 100% compatible with DCC.
