Originally, a full 26-episode series was planned, but eight were cut to make way for the development of Big World! Big Adventures! and the twenty-second series. In addition to this, Sodor Island Forums confirmed that the reduced total of episodes was needed to make up for the delayed productions of the nineteeth and twentieth series, due to The Adventure Begins being fast-tracked into Arc Productions' schedule.
 * Whilst it has been confirmed that two of the cut episodes for Series 21 would have focussed on Rosie and Bulgy respectively, the nature of the other six episodes is currently unknown.
