The Strange Sound

The Strange Sound is a magazine story.

Plot
It is a very hot day and the weather is making Thomas feel upset and tired. Thomas is looking forward to a rest at the main station once his work is done. Percy, who is shunting in the nearby yard, is feeling tired too.

The two engines begin quarreling about who was working harder but The Fat Controller tells them to stop and go for a drink at the water tower.

When the two arrive, Duck is already there. Suddenly, a quacking sound is heard. Thomas and Percy are surprised and think it's coming from Duck. It turns out it is coming from a different kind of duck, as Thomas' driver finds the animal having a swim inside the water tower.
