Supertrain was a massively promoted and extremely expensive 1979 NBC adventure drama that lasted only a few episodes before being cancelled. Along with the US boycott of the 1980 Summer Olympics, the superflop nearly bankrupted the network.
The show featured an “atom powered steam turbine” train that could travel from NYC to LA in 36 hours. Infrastructurist has posted links to the awful and campy pilot episode of the show. Here’s part one to get you started. I love that the train’s crew is right out of a 1970s disco and the board of directors are bona fide 1890s railroad magnates. This thing is a train wreck. (Layered narrative again! Bam! (Again!))
