Line 4 (Yellow Line) is a line of the São Paulo Metro, originally called Southeast-Southwest Line. When finished, it will go from Luz to Vila Sônia. The first stretch, between and Faria Lima and Paulista stations, opened on May 25, 2010. Two other stations, Butantã and Pinheiros, took more time than expected to open, but as of July 2011, they are fully operating. Actually, the line go from Butantã to Luz. In January 2011 it was announced that the new estimated opening had been postponed until mid-2011. The Butantã station opened on March 28, 2011. It is expected that the line will be fully completed by 2014. It is operated by ViaQuatro, a private company which won the public-private partnership to operate Line 4 for 30 years, which can be renewable for another 30 years. Companhia do Metropolitano de São Paulo will monitor the operation.[2]


Conceived since the years 1940s, the route of Line 4-Yellow was present in all studies for deployment of the Metro in São Paulo since. This road was consolidated in 1968 when the initial studies for the implementation of the current subway network, receiving at that time, the name of Southeast-Southwest Line. In parable form, would connect the neighborhoods of Pinheiros and Sacomã, from Jóquei Clube station to Via Anchieta station, through the Downtown, cutting East-West line of the Metro in República and Pedro II stations. Integration platforms came to be built in those two stations, but were not used. The Republic station platforms, built in the 1980s, with a further configuration of line 4, would be demolished for the passage of the tunneling machine, equipment that built the tunnel of Line 4 between Faria Lima and Luz stations, those from Pedro II station became a depôt. The consolidation of the project was only in 1993, when the basic design was first developed, already no longer including the Southeast portion, embedded in other policies of the Metro expansion and improvement of commuter trains.

Even in the 1990s, the Metro considered taking Line 4 to Tatuapé station, with the intent to relieve the Line 3-Red. This idea was discarded, having been replaced by a possible expansion of the Line 2-Green until that section. The construction of the Expresso Tiradentes (formerly Fura-Fila), designed in the administration of mayor Celso Pitta and the first section delivered in 2007, further reinforced the intention to build Line 4 only in the vector southwest of the city, from Luz Station.


On January 12, 2007, during the construction of Pinheiros station, a large part of the site's access tunnel collapsed, opening an 80 m (265 ft) diameter crater, killing seven people.[3] Several houses and vehicles were swallowed by the hole, including a minibus; four of the victims were inside. A lot more houses suffered heavy damage, with several of these being declared condemned. Following Pinheiros' accident, Época magazine, aside Rede Globo, made a series of revelations about the security of the other line's stations, then still in building stage, dispensing special attention to the Paulista station, at Consolação quarter, a more heavily populated area, where a crater like that would have claimed a lot more lives.

The line's works were kept paralysed for about two months. Because of the press' accusations, the timetable was delayed for about four months, and Pinheiros construction could only be resumed after the end of the analysis procedures designed to discover the accident's cause. The reports were delivered in August, 2008, representing a delay of almost two years on the station's works. After work on the line resumed, two teams were digging the tunnel (one from each end, planning to meet in the middle). As they approached the meeting point, it was noted that there was an error of 80 cm (2.6 ft) between the tunnels.[4] During April, 2010, at the site of São Paulo: Morumbi station, a 30 m (100 ft) crane fell while hoisting building material from the bottom of the site. The crane fell across the pavement of Ave Prof. Francisco Morato; there were no injuries and work was not interrupted.[5]


The whole construction work, carried out by Camargo Corrêa enterprises, is under suspicion of irregularities, according to the São Paulo's Public Ministry, in conformity to investigations done at the Operação Castelo de Areia (Portuguese for "Operation Sand Castle") carried out by the Brazilian Federal Police.[6]

On Lines 1, 2 and 3, the track gauge is a non standard 1600 mm, the third rail is 750V DC and under running. For Lines 4 and 5, the track gauge is 1435 mm and they use overhead pantograph, precluding any connection to the rest of the system, plus the 4 and 5 lines can't connect because the trains on the 4 line use drive-less technology while trains on 5 line are OPTO. Lines 7, 8, 9, 10, 11 and 12 (operated by CPTM) are all 1600mm and use overhead pantograph.
