An electrified-cable system is disclosed herein. The system includes first and second wires each having a longitudinally-extending uninsulated region comprising at least a portion of the circumference of the first wire, and a longitudinally-extending insulated region comprising the remaining circumference of the first wire, and an insulating connector that couples the insulated region of the first wire to the insulated region of the second wire. The system is configured to form an electrical circuit from the first wire to the second wire through a carriage in electrical contact with the uninsulated region of the first wire and the uninsulated region of the second wire. A corresponding method is also disclosed.

An integrated bollard, anchor, and tower (IBAT) system constructed as a single monolith may be formed of a single material, such as concrete or steel, or assembled from components of distinct materials, such as reinforced concrete with metal brackets, fixtures, fasteners, and so forth. An anchor (e.g., base, pad), sized to engage the ground therebelow by weight and friction, includes a mass sufficient to provide frictional stability (no appreciable movement) of the IBAT unit at each end of a track line (cable, wire rope, line, etc.), which wraps around the bollard portion of each upright (tower, fin) portion at an operational height defining the path of a trolley carried on the free span of the resulting catenary.
