EPISODE CONTEXT

As the ninth standalone vignette in Season 16's anthology format, "Sleeper Train" follows the cold-themed dread of episode 8, "Frozen," shifting the horror setting from environmental exposure to suffocating confinement. It continues the season's pattern of mining distinct, everyday scenarios for supernatural terror, all framed by the recurring kamishibai storyteller. With the season progressing deep into its collection of modern urban legends, this installment represents the anthology hitting a confident stride in atmospheric horror delivery.
