Tripped Up! is a magazine story.
It is apple-picking time at the Vicarage Orchard, and as Thomas stops at a nearby signal he whistles, which startles Jem Cole and he wobbles on his ladder. Thomas is sorry and luckily, Jem is not hurt. Trevor then takes the apples to a nearby station for Thomas to take to market. Whilst at the station, Thomas sets off too quickly and the trucks burst open and the apples spill onto the platform. Luckily, a thief who has stolen the money from the ticket office, trips on the apples and is caught.
- Despite being published in an older magazine, it was reprinted in 2010 with new illustrations.
