The vans later encouraged Diesel to pull a line of 20 trucks, with their brakes on unbeknownst to Diesel. Īccording to Salty, these vans were one of the trucks that knew his secret. They stopped their teasing towards him, when he pulled S.C. When Oliver fell into the turntable well, they were one of several trucks who teased him when returned from the works. As a result, the yard was in a terrible mess causing the twins to be late with their evening duties. On one occasion, the vans (along with other Troublesome Trucks) tricked Bill and Ben where to shunt them. Gordon tried to wheesh them away but to no avail. Another one of these vans laughed at Gordon, when he lost his dome. When Diesel failed to pull a line 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 fury and annoyance.
