I am thinking of adding a few Chuggington HO Scale trains to my collection. We just got the wooden and Diecast versions of Emery in honor of my friends Emery (AFOL Man). What do you think? Should I get a few of the Chuggington series? I don’t think I will be getting more of the wooden or diecast versions, even though they are compatible with the Thomas the Tank Engine versions. J
