Vincent Price was really cool. I recall he made several guest appearances at the time including a memorable dual guest shot on the Bionic Women. The previous review was right on the money and brought back a lot of memories. It seems there were about four episodes and they were building to some type of background regarding the "crew" of the ghost train. They referred to the "Head of the Line" several times and you always wondered who or what that was.. of course in those days it was more likely to be some religious figure than science fiction, but supernatural and scifi were neck and neck in those days. Almost like Westerns and Star Wars were about equally popular. In those days.
