Trivia

 * A planned episode concept for this series revolved around Thomas fantasising about travelling through time after seeing a replica of H.G. Wells' time machine at a science fiction exhibition at Tidmouth Museum. Had it been produced, this episode was intended to feature the original Gauge 1 model of Thomas used in the first series as part of the fantasy sequence.
 * This episode would have marked the first appearance of Thomas' original Gauge 1 model since the eleventh series episode, Thomas and the Stinky Cheese.
