The original Sao Paulo Metro stock was built by Budd in preparation for the initial segment opening in 1974. Since then, additional rolling stock has been manufactured by Mafersa, CAF, Alstom, Siemens, and Bombardier. As of 2015, the oldest trains, known as A stock, are being modernized and redesignated as J stock.
