- “The live action appealed to me as it felt like the best train set ever and I had and loved my model railway as a child.”
- ―Andrew Brenner on the original live action model series, 2012 SiF interview
Andrew Brenner (born in Key West, Florida, USA) is an English-American script writer, songwriter and singer who is the current head writer for Thomas & Friends. He started writing for the seventeenth season in November 2010 for which he wrote ten episodes, when Sharon Miller stepped down. He also wrote ten episodes for the eighteenth season, six episodes for the nineteenth season, and ten episodes for the twentieth season, three of them were story adaptations from The Railway Series book Small Railway Engines. He additionally worked as a script editor for Blue Mountain Mystery before taking over as head writer.
He is also currently head writer on "Pablo".
He previously worked on the magazine stories, starting at the beginning of their publication in 1987. He was given seasons one and two on video and was asked to adapt the episodes into magazine stories. When he ran out of episodes to adapt, he wrote original stories, several of which were adapted into third season episodes without his knowledge or consent. He stopped working on the magazines soon after. He was never credited for his work in either the magazines or the television series. Among the stories that were adapted were Henry's Forest, which was inspired by a storm that caused damage and blew trees over around London.
He was also the head writer of "Tractor Tom", "Angelina Ballerina", "Fireman Sam", and "The Cramp Twins". It also stated on his online CV that he is the headwriter for Jack and the Pack. This was later removed for unknown reasons.
