It travels using the Trans-Siberian Railway. The ranger couple utilise a crew of Spartans from the Order (among them Stepan) to keep the locomotive running and secure from outdoor hazards - such as mutants and harsh environmental conditions.
The entire train appears to consist of 4 units, with the Aurora as the locomotive, a large modified passenger car that appears to be used for storage and living quarters, another steam locomotive in non-operating condition possibly used for additional storage or spare parts, and a flatcar holding more equipment, including a long pole-like device.
However, creative director Andriy Prokhorov has said in interviews that "The Aurora will be constantly changing along the journey with more cars, different types of cars, and people that join you... ...Before in Metro you had different stations, and now the Aurora acts as your station".
- Aurora is also the name of a Russian protected cruiser. A shot from her forecastle gun is consiered to be a symbolic start of the Bolshevik Revolution in 7th November 1917.
- The Aurora is a "duplex" locomotive, with two sets of driving wheels in what appears to be a 2-8-8-6 configuration, which means a forward pilot truck with two wheels, two sets of driving wheels with eight wheels each, and a trailing truck with six wheels. In Russian configuration, this would be a 1-4-4-3, though there is no known Russian locomotive with this configuration.
