A cantilever assembly includes a cantilever arm having longitudinal fastening channels and slots in communication with the fastening channels. The assembly also includes an attachment bracket featuring a first leg portion and a second leg portion defining a seat there between with the leg portions featuring apertures. Bolts having threaded shafts are positioned through the apertures of the attachment bracket and engage the threaded bores of nut plates positioned in the fastening channels of the cantilever arm. As a result, when the bolts are turned, the nut plates engage side walls of the fastening channels and the distal ends of the bolts engage a central pipe portion of the cantilever arm.

In one or more embodiments, techniques are provided for modeling overhead line structures of electric railways that utilize a flexible, reusable structure template to automatically generate a 3D model of the overhead line structure. Each structure template includes a set of points that represent joints of the overhead line structure and components that represent elements of the overhead line structure. A feature definition of each joint and component includes properties, constraints and cell mappings. By mapping key points of reference lines for an overhead line structure to key points in an applicable structure templet for the overhead line structure, and applying the constraints and, in some cases the cell mappings, a 3D model of the overhead line structure is automatically generated. The 3D model may be a “low detail” stick representation for fast modeling, or, using the cell mappings, a “high detail” cell-based representation for very realistic modeling.

An insulating support assembly for a catenary is adapted for powering an electrical vehicle. The assembly includes a base part adapted to connect the insulating support assembly to a section insulator of the catenary, a suspension insulator extending from the base part along a reference axis, and a suspension plate suitable to be hung to a supporting pole of the catenary. The suspension plate is connected to an upper part of and is movable relative to the suspension insulator.
