The contract award was announced in January and was confirmed on September 1 by São Paulo governor Mr Geraldo Alckmin. Finance for the order is supported by a €85m loan from the European Investment Bank and the trains will be delivered within 23 months.

The 170m-long trains will feature full-width gangways to maximise capacity and designated luggage areas for airport passengers. The joint-venture overcame competition from Hyundai Rotem and CAF to secure the order.

The 12.2km extension will offer a 15-minute journey time with trains set to run at eight-minute intervals. CPTM confirmed in July that the line will open next year. Construction began on the project at the end of 2013.

CPTM recently completed a feasibility study into an extension of the line, although this project is dependent on the availability of financial resources.
