The invention is directed to an apparatus to assist a model railroad hobbyist in cleaning driven or non-driven wheels of a locomotive or car. To achieve this objective, removable and invertable embodiments of the invention are disclosed. The invention provides a convenient means for replacing a conventional track segment with a dedicated cleaning segment. In one series of embodiments, a conventional track segment is replaced with a cleaning segment; in another series, a conventional segment is mounted to a support on an obverse side while a cleaning segment is mounted on a reverse side thereof. Nonlinear rail contacts are used to establish electrical continuity between the track and the mounted segments. Removal, inversion, and replacement of the support permits the user to change the segment in use. In yet another series of embodiments, the support is rotatable, thereby permitting the user to merely rotate the support from one segment to the other.
