The Compagnie des Chemins de fer à voie étroite du Midi which was part of Baron Empain's group, received in 1898 the concession for several lines in the Pyrénées-Atlantiques.

The Chemins de Fer de Pau-Oloron-Mauléon et Tramways de Bayonne-Biarritz company was one of the companies intended to operate these lines.

The company was absorbed in 1913 by S.A. Union des Tramways.
