These are items my child used to play with. There are some scratches from use. They weren't used roughly. One power switch on an old train car is broken. They haven't been played with for several years. I think the ones I bought new (ALFA-X, Doctor Yellow, with sound) should be okay, but some were purchased used, and I think the old ones might not work. There are a lot of them, so I don't intend to check their operation. I will sell them as junk.
