The State Railways Administration of Uruguay (AFE) operates three commuter rail lines, namely the Empalme Olmos, San Jose and Florida. These lines operate to major suburban areas of Canelones, San José and Florida. Within the Montevideo city limits, local trains stop at Lorenzo Carnelli, Yatai (Step Mill), Sayago, Columbus (line to San Jose and Florida), Peñarol and Manga (line Empalme Olmos) stations. The historic 19th century General Artigas Central Station located in the neighbourhood of Aguada, six blocks from the central business district, was abandoned 1 March 2003 and remains closed. A new station, 500 metres (1,600 ft) north of the old one and part of the Tower of Communications modern complex, has taken over the rail traffic.
