Ressha Gattai Diesel-Oh

Ressha Gattai Diesel-Oh (烈車合体ディーゼルオー) is the secondary Giant Robo of the ToQgers.

Overview
Diesel-Oh is the combined form of the first 3 support ressha, not including Shield Ressha. While Diesel-Oh lacks any weapons, its raw power is more than enough to compensate. Its finising move is the Diesel-Oh spinning kick, where Diesel-Oh jumps into the air, then crashes into the enemy feet first while spinning at high speeds.

History

Diesel Ressha
The Diesel Ressha (ディーゼル烈車) is a maroon diesel locomotive-themed Support Ressha. When in full form, the locomotive is attached to a train comprised of multiple units (turning it into a diesel multiple unit, or DMU) with a boxcar and a flatbed with cargo boxes at the end. Diesel Ressha forms the arms and main body of Diesel-Oh. On its own, the Diesel Ressha has missile silos in it's engine component to fire at targets.

The Diesel Ressha is also the oldest Ressha on the Rainbow Line, and is affectionately called "Grandpa" (じいちゃん) by Right.

Tank Ressha
The Tank Ressha (タンク烈車) is an auxiliary cyan armored fuel carrier train-themed Support Ressha used by the ToQgers. It is comprised of two tank cars, one of which has a cab. The Tank Ressha can extend a hose to insert into another Ressha to pump a special fuel to temporarily supercharge a Ressha's performance. This Ressha forms the left leg of Diesel-Oh.

The Tank Ressha was one of the Ressha that was lost from the Rainbow Line during the Shadow Line's aggressive invasion, and was found in the mountains near Oumori Station, where Bucket Shadow had attempted to take over, and Right had actually found the Tank Ressha first but turned back to get food. Despite General Schwarz's tactics when he went to grab the Ressha for himself and handily bested the ToQgers on foot when they went back for the Tank Ressha, the ToQ Ressha of this Support Ressha was found by Hikari.

Car Carrier Ressha
The Car Carrier Ressha is an auxillary golden mech used by the ToQgers. It is comprised of two car-carrier freight cars, one of which has a cab at the front. It carries five cars composed of five different color for each member of the core team. It can also function as track that the other Ressha can cross. The Car Carrier Ressha was handed out to the ToQgers to get across the Darkness by Ticket.
