Trainboy 54 is a YouTuber who makes videos about his Thomas & Friends Tomy/Trackmaster customs and stories he wrote involving them. These customs were often characters from other TV shows, including Phineas & Ferb and My Little Pony. Likely because he was mocked and harassed for making the models, he has moved channels multiple times and deleted some of his older content.
Currently, all of his videos prior to 2016 are lost, including the first three seasons of his stories. Additionally, parts of the fourth and sixth season, as well as the entire fifth season, are missing as well.
