Água Branca station was one of the opened in the opening of Santos-Jundiaí railway by São Paulo Railway, on 14 February 1867. Initially, it was a rustic building. With the opening of Sorocaba Railway, which was parallel to it, Água Branca station, which was far from São Paulo, began to have importance as an integration point and cargo depot between both railways. In 1896, Vidraria Santa Marina was risen next to the station, which contributed for the industrialization of the region, which peak was the implantation of the huge industrial complex Indústria Reunidas Fábricas Matarazzo, in 1920 in the station surroundings, attracting even more passengers and cargos for the station. In the 1890s, SPR reformed many stations, classifying them as first and third classes station. Slowly, the station building was becoming smaller for the growing demand. Another problem faced by the station was Tietê River, which floods flooded the station yard, interrupting the traffic. With the river retification, between the 1930s and 1960s, the region began to suffer less with floodings. With the nationalização of São Paulo Railway, in 1946, the Federal Government signed cooperation contracts with United States, created the Brazil-United States Mixed Committee for Economic Development. Working between 1951 and 1953, the committee established basic parameters for the modernization of Santos-Jundiaí Railway, including its stations. Between mid-1950s and the end of 1960s, many stations were rebuilt, including Água Branca. The new station received large accesses and a new administrative building, opened in the 1960s, having its catwalk opened on 20 October 1976. In the 1970s, the station was planned to receive the Metro East-West line, but the project wasn't realized. Slowly, the problems with Santos-Jundiaí commuter trains grew, and the station went into decay, which peak was reached in the beginning of the 1990s. On 1 June 1994, the station and the line were assumed by the state through the CPTM. Besides it wasn't depredated during th 1996 CPTM riots, the station was closed for 6 months, along with the entire line. Currently, it is part of CPTM Line 7-Ruby.
