The original route of the Trans-Siberian Railway covers Moscow, Yaroslavl, Chelyabinsk, Omsk, Novosibirsk, Krasnoyarsk, Irkutsk, Ulan-Ude, Chita, Khabarovsk, and Vladivostok.
The Trans-Mongolian route implies going from Ulan Ude to Ulaanbaatar and then to Beijing.
The Trans-Manchurian route, in its turn, goes to Beijing right after Chita, covering the Manchurian part of China.
