It was an atomic powered train that went 200mph. Considered one of the biggest and most expensive flops in television history. The show's mock-up set alone cost $5 million (almost $16 million in today's dollars) and the show's failure helped put the NBC network near the brink of bankruptcy.
Here's the model after it accidentally crashed... a perfect metaphor for the show's fate...

But no other network show centered around a train, so I loved it. I was too young and enamored with this fact to realize the campy show and the acting in it actually sucked.


Not actually shot at Portsmouth unfortunately, but they found a pretty good stand in.
