Koutetsujou

The Koutetsujou (甲鉄城, lit. Iron Fortress) is a Hayajiro from Aragane Station. After crossing through Hayatani Station and stopping at Aragane Station, it was used to evacuate Aragane's survivors once the station was breached and overrun by Kabane.

History
The koutetsujou was first seen being attacked by kabanes, presumably going to Aragane Station.

West Gate Breach Arc
The Koutetsujou was being maintained by Ikoma and his friend Takumi when they found a kabane heart, which Ikoma took as a sample for his research.

Design
The Koutetsujou looks almost like a steam locomotive train. It is made almost entirely on metals and it has numerous holes found in its body to shoot the kabanes outside. A master key is required to operate the Koutetsujou, which can be inserted in a keyhole in the crew compartment.
