DenLiner
The DenLiner (デンライナー, Denrainā?) is Den-O's transportation system, a bullet train mainly used for traveling to other times and launching attacks against Gigadeaths. The DenLiner arrives when a person holding a Rider Pass touches a door while the hour, minute and second of time are the same. It is able to travel to different times when a Rider Pass, along with a Rider Ticket that contains the date in which an Imagin has traveled to, is inserted into the DenBird, while docked in the DenLiner. The date then becomes the DenLiner's new destination in time.
The DenLiner has multiple forms, split throughout eight cars. When not using a certain form, the DenLiner's eight cars are linked up, forming one large train. These railroad cars only disconnect and change form when Den-O is in the corresponding form. Form-specific cars can also link up with other cars in various orders to provide additional weaponry when fighting Gigandeaths. Furthermore, the DenLiner can link up with the ZeroLiner for more power. When Den-O enters Climax Form, the DenLiner is affected by the power surge and enters Climax Mode (クライマックスモード, Kuraimakkusu Mōdo?), turning a golden color with an intense fiery aura around it.
The DenLiner also has various non-combative cars that separate from the Gouka during battle and serve as settings for the television series and movies. These include the dining car where most of the series takes place, a bath car used several times late in the series, and the sleeping car where the group meets the Swan Imagin Sieg.
