The Trans-Siberian Railway is a network of railways connecting Moscow with the Russian Far East and the Sea of Japan. It is the longest railway in the world. There are branch lines to China through Mongolia and Manchuria, with service continuing south. In March 1891, the future Tsar Nicholas II personally opened and blessed the construction of the Far East segment of the Trans-Siberian Railway during his stop at Vladivostok, after visiting Japan at the end of his journey around the world. Nicholas II made notes in his diary about his anticipation of travelling in the comfort of”The Tsar’s Train” across the unspoiled wilderness of Siberia. The Tsar’s Train was designed and built in St. Petersburg to serve as the main mobile office of the Tsar and his staff for travelling across Russia.
