Big is Beautiful is a magazine story.
Thomas enjoys teasing Harvey about his size. Harvey is a large engine and cannot fit through some of the island's tunnels. One hot summer's day, Harvey runs out of water and has to fetch some out of a river. Thomas warns Harvey about his bad experiences with fishing in the river. Thomas chuckles so hard he forgets to slow down around a sharp corner and lands in a ditch. The Fat Controller orders Harvey to lift Thomas back onto the rails and Thomas has to admit that big can be beautiful!
