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.
