Trivia

 * This series marks the first of several things:
 * Gina and Ace's first appearances since The Great Race and Big World! Big Adventures! respectively, and two characters' first appearances in an episode.
 * Knapford Harbour's first appearance since Season 4, and first appearance in full CGI.
 * The first series since Series 18 not to have episodes written by Lee Pressman.
 * This will be Andrew Brenner's last series as head writer.
 * Emily Sharpe joins the voice cast.
 * Starting in this series, Thomas, Gordon, James and Percy gain extra rivets on their cabs, bufferbeams and smokeboxes, as well as handrails on their cabs and tenders, while Emily gains an extra handrail over her smokebox. This was done in order to make them look more consistent with Nia and Rebecca.
