\r\nPhase 2 comprises the completion of the two-station western section of the line from Butant\u00e3 to Vila S\u00f4nia, which is already used by trains travelling to and from the depot, together with the completion of three intermediate stations on the initial operating section between Butant\u00e3 and Luz. The Reais 2bn project is being financed with the aid of a $US 130m loan from the World Bank.\r\nThe deadline for technical and economic proposals is January 13 and construction is expected to resume in April.\r\nA consortium of Corsan and Corvium was awarded the phase 2 contract in 2012, but the agreement was subsequently terminated in July this year due to failure to complete works on schedule. By this time the consortium had completed only one of the stations, Fradique Coutinho, which opened in September 2014.\r\nThe interchange with the future metro Line 6 at Higien\u00f3polis Mackenzie on the initial operating section of Line 4 is due to be completed within a year of the signing of the new contract, while Oscar Freire station will open within 18 months. Services are expected to begin operating to S\u00e3o Paulo-Morumbi and Vila S\u00f4nia within three years of contract signing, which is likely to push the final completion date into 2019.\r\nWhen phase 2 is completed Line 4 will be 12.8km long with 11 stations. The first phase of the driverless line opened in 2010.
