Time-traveling train from Kamen Rider Den-O.
Depending on his current form, Kamen Rider Den-O boards a different DenLiner and pilots it via the Machine Denbird, which is connected to the interior of the cockpit.

Starting from the upper-center of this image and moving clockwise, they are Gouka (red), Isurugi (blue), Rekkou (yellow), and Ikazuchi (purple).

Gouka

This is the DenLiner corresponding to Sword Form. Its second car is equipped with a sonic cannon modeled after a dog’s head, the third car features a bomb-launching device modeled after a monkey, and the fourth car is capable of firing missiles modeled after a bird.

Isurugi

This is the DenLiner configured for Rod Form. It consists of a single carriage, and the radome mounted on its roof can detach and transform into an unmanned, sea-turtle-shaped aerial unit for combat.

Rekkou

This is the DenLiner configured for the Ax Form. It consists of a single carriage and fights using a blade that extends from the front, along with five axes that deploy from the sides.

Ikazuchi

This is the DenLiner that corresponds to the Gun Form. It consists of a single carriage, which can transform into a dragon-like form to fire beams in battle.
