Happen to see this video of train travel from Paris to Moscow. The travel is for more than 3000 kilometers and the train travels it in just 36 hours. The most interesting part is that the train is converted from European normal gauge (1435mm) to Russian broad gauge (1520mm). This is done by replacing the bogies of each coach. The train is uncoupled and each coach is positioned at a hydraulic hoist. With the help of a crane the screw-type couplings are removed and replaced by Russian automatic couplers. Now the wagons are lifted off from the bogies by the hydraulic hoists and the bogies are pulled away by a cable winch.
