Chuggington, another railway-based children's show that rips off Thomas the Tank Engine directly, has pretty much all the same fridge horror elements. But it's made more disturbing by how the central characters have the children's voices and psychological ages of about four to five. Their mobility is similar to wheelchair bound paraplegics who have had their hands cut off but are still able to use their elbows to pick up things and control said wheelchair. But they are pretty happy. This is probably an accurate representation of how younger children with severe physical disabilities and limited life expectancies act. It's still pretty horrifying to watch, though, especially since the engines were designed like that by humans.
