The DenLiner (デンライナー Denrainā) is Den-O's transportation system, a 'Shinkansen' (bullet train) mainly used for traveling to other times and launching attacks against Gigandeaths. 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 Den-Bird, while docked in the DenLiner. The date then becomes DenLiner's new destination in time.
