## Historique:

La voie ferrée de Toulouse à Bayonne a été créée entre 1861 et 1867 et a été électrifiée entre 1922 et 1930. La ligne à haute tension du Bouhet à Lannemezan a quand à elle été créée en 1914 et fut originellement exploitée en double ligne biphasée à 28 000 volts afin d'électrifier la caténaire de la voie ferrée.

Suite à la normalisation dès 1921 par l'État pour un courant continu en 1500 V, une restructuration du système de la caténaire a été réalisée en 1923 avec la réutilisation des supports d'origine pour la création d'une ligne triphasée à 60 KV.

Entre 1948 et 1949, la majorité des pylônes sont légèrement modifiés afin de placer les conducteurs sur un plan quasi-horizontal.

Comme elle permettait de raccorder une partie de la voie ferrée au réseau électrique, elle suivait intégralement la ligne de chemin de fer à quelques exceptions près. La ligne fut démontée en 1984 suite à la reconstruction d'une ligne indépendante aux supports caténaires. Les anciens supports caténaires de la ligne devait déjà avoir disparu depuis 2019 suite à la modernisation de la voie ferrée mais un grave accident qui s'est déroulé en 2018 au niveau de la rampe de Capvern a arrêté les travaux.

## Futur:

Modernisation des caténaires (travaux initialement prévus de 2019 à 2021). Les travaux sont arrêtés suite à un grave accident qui s'est déroulé en 2018 au niveau de la rampe de Capvern.

## Description du tracé:

* La ligne à haute tension débutait au poste du Bouhet et remontait la vallée de la Lène en longeant la voie ferrée jusqu'à la gare de Capvern.
* Elle faisait une boucle au sud de la ville pour se redirigé vers l'est, en direction de Lannemezan.
* Après avoir croisé la D17, elle longeait les lignes à 60 KV reliant Arreau à Lannemezan et reliant Arreau, Beyrède en Piquage et Lannemezan jusqu'au poste électrique a quelques mètres après la gare.

## Nouvelle tension:

1. Ligne 63 KV - (Le Bouhet-Lannemezan) - Piquage.
