Catch! is a magazine story.
Mrs. Kyndley has an urgent parcel to give to Thomas. As she walks onto the platform Thomas is pulling away. The porter grabs the parcel and throws it to Thomas' guard. The parcel is for the Fat Controller, so they have to give it to Duck at the next station. But, Duck is pulling away. Thomas' guard throws it to the porter. The Fat Controller is furious. The parcel is a scarf for Sir Topham's birthday.
- The guard is in Thomas' cab, when he should have been in Clarabel.
