In 1879, the first railroads went into operation between Yekatarinenburg, Perm and the main factories in the Urals. The mining railroads promoted the development of trade and new economic areas. Thus, Yekatarinenburg became a large railway center, a connecting link between the European part of Russia and Siberia. Perm made it possible to link river transportation and railroads. One of the main railroads ran along the banks of the Kama.
