When Diesel failed to shunt a rake of old trucks, some of these vans were seen singing a rude parody of "Pop Goes the Weasel" called Pop Goes the Diesel, much to Diesel's annoyance. Another one of these vans laughed at Gordon, when he lost his dome. Gordon tried to wheesh them away but to no avail.
On one occasion, the vans (along with other Troublesome Trucks) tricked Bill and Ben where to shunt them. As a result, the yard was in a terrible mess causing the twins to be late with their evening duties.
When Oliver fell into the turntable well, they were one of several trucks who teased him when returned from the works. They stopped their teasing towards him, when he pulled S.C. Ruffey, their leader, apart.
The vans later encouraged Diesel to pull a line of 20 trucks, with their brakes on unbeknownst to Diesel. He pulled so hard that he broke loose a coupling and fall off the quay and onto a barge.
These vans have often been used for the Flying Kipper and have been involved in many accidents and adventures while part of the train.
