RESSHA SENTAI TOQGER? (The Romanji name for Ressha Sentai Tokkyuger)

        As the online shop is now offering some pre-orders of  Ressha Sentai Tokkyuger LunchBox ,there's a questionable about the title of its upcoming series ,it is called RESSHA SENTAI TOQGER.For me it's just like a shortcut or only a trademark for Tokkyuger. Well can you imagine these on the Tokkyugers' respective names??TOQ-1, TOQ-2, TOQ-3, TOQ-4 and TOQ-5.
