=The Buenos Aires Great Southern Railway=, equally important, with the longest mileage, operates about 3800 miles of road. Ninety per cent of the mileage is in the province of Buenos Aires, serving the important cities of La Plata, capital of the province, Mar del Plata, the famous shore resort, the port, Bahia Blanca, etc. The freight station is the largest in South America with storage capacity for 230,000 bags of grain and 2000 tons of other freight. A line goes west from Bahia Blanca through northern Patagonia to Neuquen and Senilossa, 480 miles, which is handling excellent traffic especially in cattle. Important irrigation works have been made by the railway in the Rio Negro and Neuquen Valleys. The road has a terminus in Plaza Constitución, Buenos Aires, where 35 trains daily, including express and de luxe, serve 25-30 million passengers in normal years. In 1913 besides 6,500,000 head of live stock the road transported 1,800,000 tons of wheat, 1,000,000 of corn, 227,000 of potatoes, 920,000 of lime and stone, and 2,500,000 general freight. =The Buenos Aires and Pacific=, an ambitious and adventurous road, has nearly equal mileage, 3535, some of which are leased. As its name implies, it operates the main part of the only transcontinental line of South America. In addition to the cross country line from Buenos Aires to Mendoza, and beyond that, the Argentine section of the Trans-Andine, 111 miles to the Chilian Line midway of the tunnel, amounting with branches to 1000 miles, the Company has acquired by lease and construction the Bahia Blanca and North Western Railway, now extended to Mendoza, with branches, a length of 900 miles. From Bahia Blanca a line called the Patagonas Extension has been constructed 167 miles to Carmen de Patagonas at the mouth of the Negro, giving access to northern Patagonia. Land is being irrigated with water from the Colorado River in the effort to attract colonists. It is a property which has been extended too rapidly to pay dividends at the moment, but of an assured future. On the North Western Railway wheat, barley, oats, wine, maize, cattle, sheep, and general merchandise are the freight; the passenger business is small in comparison. =The Buenos Aires Western Railway= is fourth in importance, with 1870 miles of track extending from the Once Station, on the Buenos Aires subway in the heart of the city, to sections of La Pampa and San Luis; primarily a freight road, it now carries many passengers. Electricity is used for suburban traffic. By tunnel from the Once station, freight is carried to the port, being by so much ahead of New York. With the Great Southern, the Western has leased the Midland Railway from Buenos Aires to Carhue, 320 miles. In 1912-13 the road carried over 7,000,000 head of live stock, nearly 3,000,000 tons of freight, and 1,000,000 passengers. Wheat, maize, hay, and other agricultural products are the bulk of the freight.
