and pantograph can be improved through using shock absorbing materials in the
supporting structures, in such a way as to minimize the stress and wear.

With regards to the effects of wind action, there are areas of R&D related to the
development of materials and coatings capable of withstanding the abrasion caused by
suspended particles, as well as registration arms and cantilever tubes of greater rigidity
and resistance.

Finally, the use of fibre-optic should be highlighted as a tool to monitor the facilities, not
only in the infrastructure but also the catenary and cable conduit. Spain, Germany and
Japan are actively working in this field.
