It’s 3am, and Natalia is getting ready for work. Like most people, she tidies her clothes, gathers her things, and kisses her children goodbye. Ahead of her lies a 300-mile (480km) commute to Moscow, Russia’s capital to start her 14-day shift. It will take her all the way across the world’s biggest country to the Pacific – and back. Natalia is a conductor on Russia’s main train, the ‘Rossiya’, on which the route is always the same, but every trip is different.
