S1E31 Watch Out Wilson

The trainees are practicing maneuvering rolling stock through an obstacle course. Eager to impress, Wilson decides to tackle the fire wagon. The course appears simple—until Dunbar announces they must navigate it in reverse! Wilson goes first but fumbles multiple times. Feeling defeated, he wanders away and encounters Harrison, who offers some advice: switching to a lower gear will help him maintain better control. That sounds promising!
