country until the nomination for the 2014 FIFA World Cup, when several prospective host cities announced plans to establish such systems as part of the infrastructure works initially intended to serve the event. (As the event approached, many of those projects - including expressways and light rail transit systems - were cancelled or postponed.) The Institute for Transportation and Development Policy classified the system as a Bronze-standard BRT in the 2013 Corridor Ranking. Diadema - São Paulo Extension An extension branch to the system was proposed, connecting Diadema terminal to the Brooklin neighborhood in São Paulo. Such extension was referred as Diadema-Brooklin corridor and began construction in 1986. The project suffered setbacks, including lack of funding, civil actions questioning the public bidding process, as well as challenging drainage works. Effective operation started in 2000, although the corridor works were not ready, with a single line service employing midibuses. The complete path was completed in 2010, which allowed the replacement of midibuses with large capacity vehicles. A shuttle service was initiated linking Morumbi and Berrini stations, both of them providing connections to Line 9 - Emerald CPTM stations. As a consequence the branch became called the Diadema-Berrini extension. Lines Source: ABD corridor lines and timetables Interference with future projects The São Paulo metropolitan transportation network expansion plan foresaw the need for a metro line linking southern São Paulo to the ABC region, expected with the line 18 implementation. The first sketched project claimed for a line from CPTM Tamanduateí Station in São Paulo up to Alvarengas Station in São Bernardo do Campo (as an elevated monorail). Such path overlaps the Ferrazópolis-São Bernardo branch of the BRT, and the design of the line suggests its suppression in favor of the rapid transit structure and a city-owned bus corridor. Such a proposal showed two setbacks: the need to partially terminate the contract with the system operator (thus requiring a compensation fee), and the suppression of a successful transportation mode (measured in Pkm). Those risks endangered the whole monorail project, and drove the São Paulo government to split its implementation, in favor of building the branch from Tamanduateí to Djalma Dutra (a station in São Bernardo) only. The latest transportation map depicted the continuation of São Bernardo-Ferrazópolis branch as well as line 18 "in construction", although effective work on that metro line weren't started (although the Portuguese legend in the map shows the segment
