The scene of Henry and Gordon being confronted by Donald and Douglas at the sheds is not present in either of the leaked scripts for the episode.Three shots originally filmed for this episode were used in the episodes Saved from Scrap and Break Van.In an early dialogue and visual script for the episode owned by Twitter user TomsProps, the episode is referred to as " Hullo Twins!".Mitton also mentioned that he was in possession of all the film negatives for the episode. During an interview with Sodor Island Fansite shortly before his death, David Mitton said that the episode was halfway through filming when Britt Allcroft decided to have it cancelled, as she thought the plot would be too difficult for children to understand (most likely due to the twins switching tenders) and lacked action.The Fat Controller appears to have fallen for it, but after the passengers have left, he swings around and excoriates Douglas. The Fat Controller and the passengers question Douglas, who pretends to be Donald and tells them his cover story. Once Donald is coupled to Douglas' tender, he leaves with his goods train while Douglas stays behind with Donald's tender. The two engines switch tenders, hoping to trick the Fat Controller into thinking they were not involved with the incident. The angry passengers emerge from the siding and complain to the Fat Controller. Shortly thereafter, Thomas arrives and panics when he finds that his coach is missing. Douglas offers to do this job for Duck one afternoon, but worries about being sent away and shunts the empty express coaches and the special one, still full of passengers, into the carriage siding. Whoever takes away Gordon’s coaches must remember to collect Thomas' special one and leave it at the bay platform at Tidmouth for him to collect. Sometimes, the Express has a special coach for passengers traveling on Thomas' branch line. The Fat Controller has numbers painted on their tenders and has Duck show them around, but still plans to find out which engine should be sent back. When the Fat Controller learns about this, he goes to meet the engines, named Donald and Douglas, and discovers they have lost their numbers. However, two identical twin engines arrive instead. Work on the railway has become harder, so the Fat Controller orders a new goods engine from Scotland.
