With color-swapping as the main gimmick, the "bland" suit design starts to make sense. If there's no major details or other parts in the way the costume/editing departments can swap colors around with no problems. It also explains why the Tokkyugers are referred to by numbers instead of their colors; the numbers don't change when they swap.

And I'd be willing to guess at the reason for the color-changing too. Does everyone remember in RPM when each Ranger suit had special abilities? That could also be applied here and explain why they have to change colors.

Those two add-on Zords really bring out the detail of the main Megazord a bit more. If we get a lot of these extra Trains then that might help the apparently lackluster design. I'm not on board for a purchase yet but I might be heading towards the station. :P
