Build DaiOh
Build DaiOh is the Warrior Mode of the Build Ressha. The back Ressha fold to form the legs and the front Ressha fold down to become the arms. The crane atop the front Ressha becomes the mecha's head. The mecha's movement depends on a series of pulleys and levers. Each one responsible for a specific limb. ToQ 6gou has semi-complete control over the mecha via the cockpit. However, Build DaiOh's maximum control and performance requires simultaneous manipulation of the levers. The other ToQgers play a vital role in Build DaiOh's performance, as they can operate the controls that ToQ 6gou cannot. The cockpit was later modified in order to allow ToQ 6gou to operate Build DaiOh on his own".

The result of the combination of the Build DaiOh and ToQ 6gou's first mecha, the Drill Ressha. During Build DaiOh's debut, the Drill Ressha has been stolen and used by an ordinary Kuliner train-mecha.
