History
The original station was a simple stop put in operation on 9 May 1843 by Compagnie du chemin de fer de Paris à Rouen. Il was a hundred meters northern and was named Étoile de Conflans.

After the classification yard extension and Achères-Pontoise railway was put into service, the station was given the name Achères-Embranchement in 1877. A second building was added next to the first in 1882.
