The company's successful operation can be seen from its freight revenue of 18.6 billion U.S. dollars in 2016.Union Pacific’s freight traffic includes agricultural products, automotive, chemicals, coal, industrial products and intermodal freight.
In 2016, Union Pacific employed close to 43,000 people, and operated just under 66,000 freight cars and 8,500 locomotives with an average age varying from 8.4 to 37.5 years. The company hauled more than 8.4 million carloads of freight on over 440 billion revenue miles.
In contrast to the freight transportation by air, road or water, the United States’ freight railroad companies operate using almost solely their own infrastructure that they maintain and pay for from their own funds: in 2016, the freight railroad industry spent almost 26 billion U.S. dollars on infrastructure and equipment maintenance. In the last decade, Union Pacific invested some 33 billion U.S. dollars in its rail network and operations.
