The two wires do not contact (although the bow collector or pantograph is briefly in connection with both equally wires). In typical service, The 2 sections are electrically connected; based on the technique this might be an isolator, fixed contact or a Booster Transformer. The isolator will allow The existing on the segment to become interrupted for maintenance.
Two overhead conductor rails for a similar observe. Remaining, 1,two hundred V DC to the Uetliberg railway (the pantograph is mounted asymmetrically to gather present from this rail); suitable, fifteen kV AC to the Sihltal railway Some railways used two or three overhead lines, typically to carry 3-section present.
