Hmmm.... well Magic Kingdom is a live TM held by Disney. Unlikely any other end-user would ever touch that domain name. Its a "dangerous' domain name to hold especially with Advertisement on the parked page that showes "competing" links to that of the TM holder.
The others, you need to really ask yourself how could these names be used in commerce and the answer is - not easily. ElectronicTrain might have the most value of the rest, because you could potentially sell train sets, ect. I know there is a reasonable market for that kind of hobby.
Value wise? To an end-user - probably around the $400-500 mark. Reseller, little, maybe between $10-20. The others just dont strike me as desirable names for other business which makes them limited to about their registration costs in value.
