History

Project and manufacturing

During the modernization process of Line 8-Diamond, CPTM identified the necessity of operation of 36 trains. Due to the company's financial unavailability, a public-private partnership was considered with a train producer. CPTM would hand over 24 Series 5000 trains and workshops in Presidente Altino Yard and the private company would have to build 12 new trains, besides being responsible for the fleet maintenance, paid by CPTM.^[2]

The PPP process was launched on 27 May 2009, with an estimated initial investment of the private partner of R$900 million (US$450.1 million) and R$200 million (US$100 million) from the state government for 20 years. The bidding was won by Paulist CTrens consortium, composed by Construcciones y Auxiliar de Ferrocarriles and Inversiones en Concesiones Ferroviarias.^[3] However, after the contract signing, the consortium chose to build 36 new trains, financed by the Brazilian Development Bank.^[4][5]

Operation

The first Series 8000 trains were presented during the reopening of Barueri station, on Line 8-Diamond. The first commercial trip occurred on 6 February 2012.^[6]

On 7 July 2019, due to an operational need, the Series 8000 trains began operating on Line 9-Emerald, with the composition 8013–8016.^[7]

Due to the concession of lines 8 and 9 on 30 August 2021, 4 Series 8000 trains began operating on Line 11-Coral, with prediction that all of units will operate on this line.^[8]
