The Água Branca station was inaugurated in February 1867 by the São Paulo Railway and was located on the main line in the Município of São Paulo, 7 km northwest of the city centre. The line changed hands several times: in 1948 to E.F. Santos a Jundiaí, in 1975 to Rede Ferroviária Federal, in 1984 to Cia. Brasileira de Trens Urbanos (CBTU) in 1984 and Cia. Paulista de Trens Metropolitanos (CPTM) in 1994 until today. So, the station remains in operation to this day.
The station post office came into being in July 1887, according to the Rio press:
The imperial postmark is probably this one, as illustrated by R. Koester in Carimbologia I (1961):
Der Bahnhof Água Branca wurde im Februar 1867 durch die São Paulo Railway eingeweiht und lag auf der Hauptlinie im Município von São Paulo, 7 km nordwestlich der Stadtmitte entfernt. Die Linie wechselte mehrmals den Besitzer: 1948 zur E.F. Santos a Jundiaí, 1975 zur Rede Ferroviária Federal, 1984 zur Cia. Brasileira de Trens Urbanos (CBTU) und 1994 bis heute zur Cia. Paulista de Trens Metropolitanos (CPTM). Also bleibt der Bahnhof bis heute in Betrieb.
Das Bahnhofspostamt entstand im Juli 1887, wie die Presse aus Rio mitteilte:
Der kaiserliche Poststempel ist wahrscheinlich dieser, wie durch R. Koester in Carimbologia I (1961) abgebildet:
