Incredibly successful {{Western}} series about a group of pioneers heading out west after UsefulNotes/TheAmericanCivilWar. The show lasted for eight seasons (1957-62 on Creator/{{NBC}}, 1962-65 on Creator/{{ABC}}), thanks in part to the broad range of storylines that its WalkingTheEarth format provided. These days, however, it's more well-known for being the first two of those [[WagonTrainToTheStars five famous words]] Gene Roddenberry used to pitch ''Series/StarTrekTheOriginalSeries''.

* AdventureTowns
* ActorExistenceFailure: Series star Ward Bond unexpectedly died of a heart attack in 1961, necessitating a change to John [=McIntyre=] as the new lead. Interestingly, no episode actually deals with Maj. Adams' (Bond's character) leaving/retiring/dying, and so the next episode is [=McIntyre=]'s character taking over from a tyrannical replacement played by Creator/LeeMarvin.
* TheChiefsDaughter: In "The Charles Avery Story," some soldiers are escorting a chief's daughter (played by Oscar-nominee Susan Kohner) back to her people with a peace treaty signed by the President. When they come under attack and their mission is threatened, Flint agrees to aid them.
* DomesticAbuse: The title character of "The Emily Rossiter Story" (played by Oscar-winner Mercedes [=McCambridge=]) is married to an abusive man.
* EvenEvilHasStandards: In "The Mary Halstead Story," Tracey, leader of a gang of bandits, becomes obsessed with vengeance on Tommy Nichols for killing Earl, the previous leader of the gang. But when he finds him, Earl's mother, Mary Halstead, defends Tommy, saying her son would listen to her and spare him. Tracey figures Earl would want him to listen to Mary, so he does, and even guns down one of his own men who wanted to kill Tommy ''and'' Mary.

* RedBaron: Earl "Laramie Kid" Halstead in "The Mary Halstead Story."
* StartsWithTheirFuneral: "The Lita Foladaire Story" starts with the death of the title character, the wife of an old army friend of Adams. His investigation leads to numerous flashbacks to her life, after which he feels he knew her very well.
* SyndicationTitle: ''Major Adams, Trailmaster'' (Bond episodes); ''Trailmaster'' (post-Bond episodes)
* {{Tomboy}}: Judy Rossiter in "The Emily Rossiter Story" wears pants and is a pretty good shot with a rifle. She's a bit of an ActionGirl, too, and [[spoiler:shoots one of the bad guys dead in the climax]].
