So I had no idea where to post this as there's not a general other form. One of the arcade pages I follow has happened upon the below.
I am not the seller, and I figured this would lead to more conversation so I didn't want to put it in for sale..

On our list of amazing finds, this one is towards the top of the list. While picking arcade machines out of an old chicken house, we came across the actual train from the 1979 Television show “Supertrain”. It had been sold by NBC to a model train manufacturer in Philadelphia that had tried to sell it in the early 80s and when that company went bankrupt the train was abandoned in its old headquarters. Some time later a cabinet maker bought the contents of the building and sold the train to the guy we bought it from. It had been stored for almost 20 years in the top of a barn until today!
The train is almost 30 feet long, comes with about 50 feet of track, all nine cars (one engine car) and is truly the only one to exist. The first one built crashed and was destroyed.
The cost for NBC was over $250,000 to build as it was all by hand and very detailed. The show almost put NBC into bankruptcy as the ratings were so terrible and the star of the show was this train essentially. Great piece of television history that belongs in a museum or a collection where it can be seen again!
Junk got piled on a few of the cars so it will need some repairs but is all there and truly a rare historical find!
Lots more photos in the comments!
