So, then, there are no authoritative standards to determine the quality of the internals of a train? If its parts, function, performance, etc are at all good, and it runs as if it just came from the factory, or indeed if it doesn't even run? If not, then why not, if even the boxes of toy trains have a complex rating system? Isn't the question of how well a train runs--which is its purpose--particularly important? After all, that's what they were made for.
