This show is often mistaken for Supertrain, which was based upon Love Boat while this show was based more on Fantasy Island. The train only really appeared as a bookend to the segments. The premise was that the train was a means to travel back in time and give people a second chance to change the past. But the segments themselves took place outside the train.
Even though the show starred Vincent Price playing a similar role to what Ricardo Montalban did as Rouke, Price would only appear at the beginning and end of segments whereas Rouke appeared throughout the show, often appearing as part of the guest's fantasies. Price was more of a host in the vein of the hosts on radio dramas. It's the lack of Price's appearance in the segments that tended to put viewers off.
Because it did so poorly it never had any repeats or releases. Only those who watched the show when it aired are likely to have ever seen it. Although there are no VHS or DVD releases of it, it's possible it could someday get a DVD release because of Price's appearance in the show but because it's so poorly remembered there's unlikely to be enough demand for it. But aside from the Price segments the show was forgettable.
