- "Silly old Thomas,
All soot and steam,
Your whistle makes a nasty scream!"
- ―The trucks
Musical Trucks is a magazine story.
Thomas is shunting trucks but, as always, they are being troublesome and singing loudly. Later, Thomas has to take some children to the Town Hall to sing for the Mayor. Then he takes them back to the station where they also sing. Afterwards, Thomas goes back to his shunting and the trucks are being naughtier than ever.
Thomas thinks of the choir and asks the Fat Controller if the trucks could sing for the railway staff. The trucks enjoy singing to an audience and make up a new song, in which they apologise to Thomas for being so troublesome: "We're sorry Thomas, our big thanks to you. We promise not to be such trouble in all that we do!"
