Christian Wolmar expertly tells the story of the Trans-Siberian railway from its conception and construction under Tsar Alexander III, to the northern extension ordered by Brezhnev and its current success as a vital artery. He also explores the crucial role the line played in both the Russian Civil War -Trotsky famously used an armoured carriage as his command post - and the Second World War, during which the railway saved the country from certain defeat. Like the author`s previous railway histories, it focuses on the personalities, as well as the political and economic events, that lay behind one of the most extraordinary engineering triumphs of the nineteenth century.
