Bertie is badass!! Yes a bit out of proportion, (no more than HitToy's Kevin) But he's built just like a legitimate Plarail engine!! Quality and efficiency in design. The original, though better proportioned, runs clunky (on a poorly designed) road, with that tiny switch on the bottom, and feels fragile. The back coupling is great too!! I am hoping he can haul a long line of cargo!! Relax... ITS ONLY MAKE BELIEVE!! 
Play nice & have fun!!
