Ah, now I see what the fuss was about, motorised artic's I didn't even know they were made. It's a shame they didn't put somewhat better detailed models on the back of them after all Tomica make lots of nice diecast cars and trains. But even so a great find and I can fully understand the trepidation while waiting for them to get here just in case something happened to them!
Happily collecting things all my life...
