The Siemens-Schuckert Orenstein & Koppel 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 from 1934 to 2016, with cars refurbished by the Emepa Group and Alstom continued to function on the network till 2017.

La Brugeoise cars were Buenos Aires Underground (Subte) Line A rolling stock since its inauguration in 1913 till 2013 when replaced by new Chinese stock. They were built by the Belgian railway rolling stock manufacturer La Brugeoise et Nivelles between 1911 and 1919 for the Anglo-Argentine Tramways Company's first underground line. They were originally designed to run both as metro and tramway cars, but they were refurbished in 1927 for underground use only. They became the oldest underground rolling stock in commercial service in the world as well as a tourist attraction and part of Buenos Aires cultural heritage.
