I seem to remember the intro to the show having the train-car traveling amongst some barren mountainous terrain. I seem to remember that each section of the car-train had a different purpose, like the medical car, and the weapons car, etc.
I don't think it ran for more than a season, possibly not even completing a full season. It was live-action. It was on US television, and I don't remember any accents, so I am guessing it was American.
