The Siemens-Schuckert Orenstein & Koppel (normally abbreviated to Siemens O&K) is an underground car formerly used on the Buenos Aires Underground first built by Siemens-Schuckert and Orenstein & Koppel in 1934, 1937 and 1944 with a smaller number of cars built in Argentina during the 1950s. The Siemens O&K rolling stock made up the entirety of the trains used on the three lines built by the Hispanic-Argentine Company for Public Works and Finances (CHADOPyF) and has since served on every line of the Underground (with the exception of Line B, which uses third rail electrification) from 1934 to 2016, with cars refurbished by the Emepa Group and Alstom continued to function on the network till 2017.
As such, it has been the most widely used rolling stock in the Underground's history, and second only to the Brugeoise cars in the number of years served, being the oldest cars in circulation at the time of their retirement in 2016.
