A sliding contact for a toy rail vehicle has a body part having a convex slide face and a depression which is provided in the convex slide face and arranged so as to form on the latter an edge by which said slide face linearly contacts with a current-conductive rail and which removes extraneous particles from the current-conductive rail during sliding over the latter. The depression may have a circular cross-section so that the edge formed by the depression is annular. The depression may have a diameter which exceeds the width of the rail so that two curved edges are formed one of which is a leading edge, whereas the other of which is a trailing edge. |
