The distinctive poles supporting the overhead have all been recovered from former tram and trolleybus systems, in many cases restored to their original length by specialist welding. They are set in concrete to a depth of about 2 metres. The trolley wire is grooved copper alloy, 4/0 gauge (80 sq. mm), suspended either from bracket arms or on span-wire construction, at a normal height of 6 metres. A second (negative) wire is provided in the Depot area, for safety earthing purposes, and for test-running the trolleybus. The trams are all fitted with trolley poles and carbon-slipper trolley heads, and return their traction current via the running rails. Overhead fittings have been salvaged from the Newcastle, South Shields, Tees-side and Bradford systems, and in the Town area period fittings have been used wherever practicable. Trams use a single wire with the negative route via the rails, whilst trolleybuses use a pair of wires, the negative being one of this pair.
