“Hello number one!”
―Nia greeting Thomas by his number.

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, but when Sir Topham Hatt asks her to take Thomas' coaches, Annie and Clarabel to pick up passengers and take them to Knapford Station, Nia has great trouble finding the right platform.
