The government began refurbishing and investing heavily in the country's freight network from 2014, beginning with the re-nationalisation of the Belgrano Cargas freight operator. Further investment of US$2.5 billion has been agreed with China in an effort to improve freight capacity throughout Argentina and refurbish ageing track segments. Through this investment, the government ordered 1000 freight wagons from Argentine state-owned company Fabricaciones Militares, while the deal with China included the purchase of 100 locomotives and 3,500 carriages from the country. This investment was doubled to US$ 4.8 billion in September 2015.
