Description - You aerial line, can be functional or inactive. Then, besides positioning the poles and the elements of aerial line, it needs to handle their electrification and the dissection, that it is not necessary in case of feeding in digital. If she is preferred to have her inactive instead, as aesthetics of environment, is that is only only enough to position the piles and the aerial line so that to respect the measures. 
Typology  - You typology of the electric line, is that in use on the Italian lines. The piles of the Italian Railroads of the State are essentially founded on the pole Mannesman said guy "M" and as in the reality, on the railroad model  one different types of poles are found.   
  The pile serves to sustain the weight of the line it airs, it has a base in cement, and it decreases upward from the lower part. Provided of an arm of support with one or more connecting rods, sustain the insulators and the arm of polygon. And' important to verify that during the positioning of the pile, these you are not found inside the outline limit of the passage.

  The insulators in the reality, electrically separate the metallic pole from the line to tall tension. But in the modelling, such isolation is not essential.

  The arm of polygon sustains the aerial line, and since in the rectilinear lines it has to follow a' course to zig-zag, in how much as in the reality it allows a' constant usury of the surface of contact of the trolley, will have to use him poles with arm of polygon it interns and external. In the curved lines, it needs to set attention not to make to follow to the aerial line the bending of the platform (in the reality this is not possible, because the thread would flex) therefore it will be had to position the poles in such way that the thread of contact doesn't go out of the limit of side move of the platform.

The poles -Using the articles of the firm M.A. The Train, the poles for the lines to binary only, they will be of the type 901 with external arm and  902 with inside arm. For the lines to binary double you/they can be used both the same, climbed on one opposite to the other, that the piles of the type 907 and 908 respectively to external and inside arm. Since the layout also includes various exchanges, she has been necessary to also use piles of the type to double arm art. 914 and piles to adjustable mooring art. 906. For the double exchanges English, have used the intermediary piles art. 923.  
The aerial line - For the fixing of the aerial line to the arm of polygon, this has two buttonholes, that must be inserted on the arms of polygon, the so-called ones "legs of spider" and overlapping her among them they are gotten draws her following. They also exist some articles with the buttonholes with three holes for the fixing, so that to be able to regulate the correct draught of the aerial line. I have used for the rectilinear lines the arts. 951 and 952, for the spans in curve the arts. 953 and 954 while for the exchanges and the links the art. 955. The aerial line for the double exchange English, in kit of assemblage, it is the art. 3957.  

Assemblage -After having determined the exact location of the pole, helping himself of the special dima to establish the exact distance from the axle of the platform, to perforate the plan with a point from 2 mms. and to fix the pile from the of under, with the washer and the die. Progress for the following poles, measuring from hookup to hookup, and only after having climbed on precedent drawn her, and gives the correct draught. For the piles to double arm art. 914 or to varying interaction, on which arms often happen to have to climb on three forms of aerial line, since one serves for the fixing to the pile of mooring, on the legs of spider there is no space to sufficiency, sees the scale. The job to be done, is to settle to pond, after having cleaned for well the line of aerial line, the three pieces, watching out for not to obstruct the holes. With some patience, and helping himself with a small wood fillet on which to fix the pieces of aerial line with some honey mushroom, easily succeeds us. In the curves they are used the piles that hold thrown the aerial line toward the outside, but in every case, it needs to give the correct draught to allow the creeping of the trolley without excessive moves, that could make to make leeway him. Then he proceeds line after line to insert the whole areal line and the piles (line) so that to have on the railroad model one a really realistic aspect.
