The Liberator(?) (Presuming it's the actual name) is a Hayajiro currently used by the Hunters, who fight off the Kabane. It first appears in Shitori Station.

History
The Liberator was first seen making an appearance at a tunnel in Shitori Station. On board was Biba, a son of the current Shogun. Other known passengers are the Hunters, an independent force that eliminates the Kabane.

Known Passengers

 * 1) Biba
 * 2) The Hunters

Design
The Liberator looks almost like a steam locomotive. It is made almost entirely of heavy metal components. It is possible that a master key is required to operate the Liberator(?), which can be inserted in a keyhole in the crew compartment.

The locomotive has a unique purplish brown color, with 2 headlights on each side.

It is possible that the locomotive cab is located at the very front of the locomotive. However, more information is needed, and will be revised when Episode 8 (or later) is released.

The locomotive is probably capable of running at very high speeds as opposed to ordinary steam locomotives, since it's engines have high output due to efficient vapor compression.

Trivia
The appearance looks similar to a 2-8-8-2 steam locomotive. It has 2 wheel leading trucks, with two sets of eight driving wheels, and a two-wheel trailing truck.

Notice: The (?) next to the 'Liberator' is there due to the current insufficient information of the locomotive's actual name. It is possible that the locomotive's actual name is something else. For now, it is currently nicknamed, "Liberator" as quoted from a citizen in Episode 7. ''"Long Live the Liberator!" -Citizen in Shitori Station''
