I recall a movie in my early days. I saw it in the 70s or early 80s. I think I saw it on either  HBO, or Cinemax or perhaps Movie time  -some pay per view back in the day. It was color.  Anyway, what I remember. Is a train going through the desert, like in the old west and there was this cult or something, these things, they looked like grim reapers, got on the train and killed just about everybody -can’t remember why or the plot. I can’t remember if the grim reapers were people dressed in the clothes or if they were really posed as super natural beings. I think some escaped the train and the reapers hunt them down or something.  I was young and scared so some info I have forgotten. In any respect the film looked like it was shot in the wild west time period and If I recall the grim reapers rode horses to get on the train.

Thanks if you can answer this or investigate.
