The first steamboat on the River Ob, Nikita Myasnikov's "Osnova", was launched in 1844. But early beginnings were difficult, and it was not until 1857 that steamboat shipping started developing on the Ob system in a serious way. Steamboats started operating on the Yenisei in 1863, and on the Lena and Amur in the 1870s. While the comparative flatness of Western Siberia was at least fairly well served by the gigantic Ob–Irtysh–Tobol–Chulym river system, the mighty rivers of Eastern Siberia—the Yenisei, the upper course of the Angara River (the Angara below Bratsk was not easily navigable because of the rapids), and the Lena—were mostly navigable only in the north-south direction. An attempt to partially remedy the situation by building the Ob-Yenisei Canal was not particularly successful. Only a railway could be a real solution to the region's transport problems.
