“Hey there, number four."
"Huh, she's already forgotten our names."
"No she hasn't, Gordon."
"She's just practicing her numbers.”
―Nia, Gordon, Annie and Clarabel

Counting on Nia is the twenty-fifth episode of the twenty-second series.


Nia is a really clever engine and knows all sorts of things, including the names of all the stations and how to deal with problems. One day, the Fat Controller asks her to take Thomas' coaches, Annie and Clarabel, to pick up passengers at Knapford Station. Unfortunately, she constantly keeps going to the wrong platform until Annie and Clarabel direct her to the right one.

While taking her passengers, Nia goes past some speed limit signs without slowing down and comes off the tracks at a digger site. This upsets Nia at the thought of having let the Fat Controller down. When Annie and Clarabel attempt to cheer Nia up, she confesses to them that she cannot read numbers (which was why she had trouble getting to the right platform and could not slow down at the speed limits). With Annie and Clarabel's help, Nia begins learning numbers and starts seeing them all around her. She even begins calling the engines by their numbers.
