Agnes, Ruth, Lucy and Jemima are coaches on the Skarloey Railway, whilst Beatrice is a guard's van. The coaches like all the engines, Sir Handel least of all for referring to them as "cattle trucks". They also were mistrustful of Skarloey at first for being bouncy. Agnes is a deep-voiced first-class carriage who looks down on the others, who are third-class. Agnes appears to be the leader of the five. All four coaches look down on Beatrice, and claim that she "smells of fish and cheese". Beatrice is, however, very useful. She has a ticket booth and an emergency buzzer, and sometimes even carries passengers when the coaches are full.
