Omsk
Location

Omsk is in the south of the West Siberian Plain, along the banks of the north-flowing Irtysh, at its confluence with the Om River. The city has an elevation of 87 meters (285 ft) above mean sea level at its highest point.

Omsk is an important railroad hub and is the junction point for the northern and southern branches of the Trans-Siberian Railway. The city also serves as a major hub for the regional highway network. 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. Omsk is served by the Tsentralny Airport, which offers access to domestic and international (primarily, German and Kazakh) destinations, making the city an important aviation hub for Siberia and the Russian Far East.

It is about 450 km (280 mi) north of Kazakhstan's capital Astana, and 600 km (370 mi) west of Siberia's largest city, Novosibirsk.
