Simply great kids anime and as a teen I really enjoyed this too as a Shinkansen fan to combine them with mecha is super cool the plot is surprisingly fun and good paced. Wish they could include other shinkansen such as the e4 max 0-300 series too but it’s fine. Kids love this in Japan and maybe adults too and I enjoyed the story more than bleach filler lol. The battle scenes were cg but didn’t mind cause it fit in. I love the sound design too with the transformation scenes and it was pretty good. Simple story but the gimics and plot makesshinkalion really good
