The second line (B), built by the Lacroze railway-tram group, was inaugurated in 1930. Finally, in 1933 a third company began work on a network that would almost double the length of the previous ones: the Compañía Hispano-Argentina de Public Works and Finance (CHADOPYF).
The current network, with more than 64 km of extension, has 6 subway lines, a Premetro line and 108 stations.
