Wrong Train to Brimstone - S1-E4
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)
Wrong Train to Brimstone - S1-E4
Continuity mistake: While Heyes and Curry are guarding the gold shipment, Heyes' hat keeps changing positions on his head between takes. First it's down over his hairline, then it's pushed back, etc. (00:26:50)
