Cleo is a road engine who will appear in the twenty-fourth series. She is Ruth's latest invention and was made out of locomotive parts, giving her an unusual appearance.


Thomas & Friends

Cleo was built by Ruth in her workshop. It was here that she first met Thomas and raced him to Knapford. During the trip, Ruth had to make several stops to drop off post and collect eggs from Farmer McColl, which caused Cleo to lose the race. She then decided to have a second race with Thomas to Wellsworth, this time going on the tracks so she could beat him. On the tracks, however, she was nearly hit by Gordon with the Express and only escaped narrowly.

Cleo later became worried when she encountered snow for the first time, though she soon began to enjoy herself once Ruth explained it to her. When the snow began to melt, she tried to save one of the snowmen at Dryaw, however it melted before she could find a way to refrigerate it. She then was treated to a surprise the next morning when Ruth created a fake snow machine for her.


Being newly-built, Cleo has very little experience. She can easily be confused or scared when faced with something she is unfamiliar with, such as when she first encountered snow. Cleo is also very excitable and enjoys racing Thomas, though this sometimes leads to trouble due to her inexperience.
