Fun stuff for it's time. An ABC Sunday Night Movie, made by Shatner largely after he completed principal photography on STAR TREK-THE MOTION PICTURE, in 1978. I happened to be on an Amtrak train in 1979,going to a "Star Trek" Convention. The conductor explained to me that that very route-Rhode Island/Connecticut to NYC, was actually the very route and train(Amtrak) on which much of the film was shot, including several stunt sequences involving a small bridge. Many "out the window" reaction shots and some of the interaction was filmed with Connecticut whizzing by the windows. The crew apparently rented out three of the cars to do some quick filming on, however the conductor had access to all of them, so he got to meet the cast used in the sequences.
Of course it was an "all star film" like many of the time. And miniatures were used in the film as well.
An interesting anecdote.
