A map of the route of the Trans-Siberian railway as it was in 1900, from St. Petersburg to Vladivostock, engraved on silver, each station marked by a precious stone, forms a broad belt around this translucent green enamelled gold egg decorated with blue and orange enamel mounts. The egg is surmounted by a three-headed Eagle in gold bearing the Imperial Crown and is supported by three Romanov Griffins each brandishing sword and shield, and mounted on a white onyx base.
Within is concealed, in three sections, a miniature replica of the Trans- Siberian Express, the engine and tender in platinum and gold, and five coaches in gold; the three parts may be connected to form a train which runs along when the clockwork locomotive is wound up above the driving wheels.
