An overhead electrical current collector arrangement comprises a housing (4) having profiled rollers (8) on its top surface which engage with a longitudinally extending guide rail (1) of substantially square cross section. The guide rail is set on its diagonals and it is suspended from its top diagonal with bus-bars (7) being carried by brackets (6) depending from its bottom diagonal into the housing (4). A current collector (18) within the housing picks up current from the bus-bars (7). <IMAGE> |
