Continuity mistake: Heyes and Curry enter the train depot at 8 pm. It's dark outside. When they come back to the platform, it's daylight. When the train leaves, it's dark again. Midway through its 60-mile journey, there's another shot of the train in daylight, followed again by more night shots. (00:07:30)Jean G
Continuity mistake: When Miss Porter enters the office, the coffee mug on Lom's desk jumps from the blotter onto the wood surface between shots, even though no one touches it. It also reverses its orientation: the handle switches from pointing left to pointing right. (00:18:50)Jean G
Continuity mistake: Harker confiscates firearms from five Devil's Hole members who are playing poker in the saloon. The sixth member is down in the tunnel, and didn't turn over his gun. Yet when the outlaws go to collect their weapons, six are given back their side-arms. (00:49:00 - 00:55:50)Jean G
Plot hole: Early in the episode, the sheriff starts going through his pile of wanted posters. According to the story line, 18 days then pass. At the end, the sheriff, standing in the exact same position and wearing the same clothes, is just finishing his search through the posters.Jean G
Factual error: Kyle strikes a match on the wooden floor to light the dynamite's fuse. In the early 1880s (the era in which this series is set), a portable flint-and-tinder kit was the common method of sparking a light. While "strike anywhere" matches had been invented by this time and were quite the rage in Europe (despite an alarming tendency to explode due to the volatile chemicals used), they were an unknown commodity on the American frontier until well after the turn of the century.

Revealing mistake: The outlaws all have their hands tied behind their backs. But the one wearing glasses, apparently unaware that he's in the shot, brings both hands up to push the slipping glasses back up on his nose, then quickly puts his hands behind his back again.Jean G
Other mistake: When Doc Donovan reads the wanted posters, the physical description of Heyes mentions dark brown hair and brown eyes, which fits Pete Duel. However, by this episode, Roger Davis had taken over the role. He has light brown hair and blue eyes.
