Built along with Variante de Poá by EFCB on 7 February 1926, only was opened with the branch on 1 January 1934. It was named after the assistant engineer of 5th Division of EFCB, Antonio Calmon Viana. Before being operated by CPTM, the station was administrated by other state companies: EFCB, RFFSA, EBTU and CBTU) which were, at the time, responsible for the lines. For decades, it kept the original structure and not passing by any great reform, what caused too much time of discomfort to commuters because of an old and outdated structure, lacking accessibility items. On 15 October 2010, the station was reopened after a great reform that preserved the main building, modernized the station infrastructure with the installing of a new metallic catwalk; elevators, restrooms and modern signaling for disabled people; public restrooms and bike parking; besides many improvements in visual communication. A new platform was built, the fourth of the station. In the station opening ceremony, a new train was delivered for Line 12-Sapphire. Many authorities were present, like Governor of São PauloAlberto Goldman, Mayor of Poá Francisco Pereira de Souza, and Chairman of CPTM Sérgio Avelleda. After the reform, a gradual increase of boardings occurred, being the only transference catwalk overloaded. In some moments, unhappy commuters chose to change platforms by crossing the tracks. After many complaints reached the Legislative Assembly, State Deputy Marcos Damasio requested to the CPTM, through the Indication No. 1492/2019, the install of a second transference catwalk between the platforms.
