Over the next few months the fleet of CSR Qingdao Sifang trains will completely replace line's current fleet of life-expired EMUs, some of which are more than 50 years old.

CSR is supplying 25 nine-car trains for the Sarmiento Line and 30 six-car trains for the Mitre Line under a contract awarded by the Argentine government in January 2013.

The first train was delivered to Argentina in February and seven sets are now in service on the Sarmiento Line. The remainder of the Sarmiento Line fleet is due to enter service by September, enabling the operation of a 10-minute interval service at peak times, while the trains will be introduced on the Mitre Line next year.

CSR is due to deliver the first of 300 new EMU cars for the 1676mm-gauge General Roca lines south of Buenos Aires in the next few months and the company also has a contract to supply 27 three-car DMUs for the metre-gauge Belgrano Sur lines. The first of these trains is also due to be delivered this year.
