Wu Houcai, CSR's technical leader in the transaction, has been working on this project in Argentina for two years. He believes that introducing the administrative system is equally important with introducing the technology.

"We spent a lot of time with the local operators and provided them with a lot of technical training. We are doing our utmost to ensure safety and maintain our brand image. The reputation of Chinese trains would be ruined if there were an accident, even if it were caused by the aged railway tracks or incorrect operation," said Wu.

By the end of 2014, 25 CSR cars had covered a million kilometers safely on the Sarmiento line, one of the intercity commuter routes in Buenos Aires, and increased the route's capacity from 241,536 passengers to 461,220 passengers a day. Local operators said some 97 percent of passengers had expressed their satisfaction with the new cars.

According to an agreement the Argentine government and CSR reached last November, CSR will establish a plant at a site of the state-owned Trenes Argentinos Operadora Ferroviaria to boost the country's railway industry.

The new plant will not only provide maintenance service, but also produce equipment and parts for CSR trains through technology transfer.

Randazzo said the plant will create new jobs, as the Chinese company uses substantial local skilled labor, and will bring the technology Argentina needs to revive its national railway industry.

CSR has been supplying trains and other rail products to Argentina since 2006. Last December, the company said it had won a 272-million-dollar contract to provide 80 locomotives and 2,000 freight rail cars for a railway renovation project in Argentina.
