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. It's ranged move is the Diesel-Oh Impact (ディーゼルオーインパクト), where it slams the right fist down on the ground, getting a explosive trail to rush to the target.

Its finishing move is the Diesel-Oh Spinning Kick (ディーゼルオースピニングキック), where Diesel-Oh jumps into the air, then blasts through the enemy feet first while spinning at high speeds.

History
to be added

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. It can also be loaded on the ToQ Blaster; giving the effect of summoning a miniature version of the Ressha ,capable of exploding like a mini-bomb.

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 (カーキャリアー烈車) 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 Imagination-powered cars that fade once they traveled too far from the Ressha, composed of five different color for each member of the core team, launching them off a built-in ramp. It can also function as track so that the other Ressha can cross. The Ressha can also be loaded on the ToQ Blaster; giving the effect of producing small colored cars as bullets.

The Car Carrier Ressha was handed out to the ToQgers by Ticket to get through the darkness Bucket Shadow made.

Cho Ressha Gattai Cho ToQ-Oh
Combining the five Resshas with the Car Carrier, Tank, and Diesel Resshas forms Cho ToQ-Oh (超トッキュウオー). It is able to fire multiple rounds from the Cho ToQ Cannons (超トッキュウキャノン) from both arms and its finishing attack is the Cho ToQ-Oh Full Burst Finish (超トッキュウオーフルバーストフィニッシュ).

According to the Conductor, Cho ToQ-Oh was not part of the original plans for the Ressha. Therefore, prolonged use can put strain and damage the Ressha.
