Omsk (Port Code: RUOMS) is a large port city in the Eastern Siberia located along the bank of the Irtysh River. At the end of the 19th century the Transsiberian Railway connected Omsk with the European part of Russia and remote Eastern areas of the country. During the 20th century, the city of Omsk has become well known as the center of political and industrial life of Eastern Siberia.
River-port facilities handle both passengers and freight, giving the city access to navigating the extensive waterways of the Irtysh and Ob River. The waterways connect Omsk with the coal and mineral-mining towns further up the river in Kazakhstan, as well as with the oil, natural gas and lumber operations of northern Siberia.
