Auxiliary limbs and weaponry are pretty much a staple of Super Sentai robots these days, and being based around a whole fleet of trains Ressha Sentai ToQger is no exception. After being snubbed for the first two releases despite being one of the first Resshas introduced in the show, the Shield Ressha makes its grand debut in the line's third wave, accompanied by the more recent Police and Fire Resshas. Since these three tiny trains probably couldn't make up a wave on their own, it has also been padded out with a re-release of ToQOh.
