This is a preowned unit that worked last Christmas -for this listing All I did was show that it does in fact power on. I did not feel like putting the entire track together – therefore the only thing else I can say is that it worked last Christmas – but here are some things noted. There’s dried decorative snow stuff the cords that does clean right off, top of a few of them probably need to be wiped down a little bit more. I did do an initial wipe down of them. The three signs on the locomotive have been reglued. One of the signs has not been reglued. It adherence is still fine There is a possibility that they will be needing an additional reglue, so do not be surprised. If when you open it the little signs on the locomotive have fallen off inside of the box supersglue, E6000 will work to reglue them. The final thing to remember is in 1996 or 1997 when it was manufactured it’s number 77 of the limited edition, but at the time the direction were not like they are now so the power unit cord for the controller looks different than the instructions themselves, but it is the original unit. Just don’t get confused when you read the instructions and the cord looks different.
