An electrical rail conductor assemblage for an in- sulated electrification system, including an elongate electrically-conducting rail having a longitudinal groove for receiving a cooperable collector shoe and for guiding it for travel along the rail. The rail has oppo- site wall portions which border the groove. The wall portions have thin wall sections with rounded longitudinal edges that constitute the mouth of the groove of the rail. The rail is covered by an essentially tubular, insulating, hollow, resilient and rigid cover member enveloping essentially all portions of the rail except for the mouth of the groove thereof. The cover member has a longitudinal cut which registers with the mouth of this groove, and curved, longitudinally-extending snap- on retainer portions that extend along the cut and are adapted to snap over the rounded longitudinal edges of the rail. These retainer portions extend in a circumfer- ential direction through substantially a full semi-circle. The advantage of the present constructions is that these retainer portions have exterior longitudinal flanges which constitute offset extensions of the opposite wall portions of the resilient cover member, to thus minimize access to the metal of the rail, and reduce the chance of inadvertent electric shock from an electricallylive rail.
