Barry the Rescue Engine is a cancelled volume of The Railway Series. It is unknown which issue it was going to be. Christopher Awdry has stated that the book had been created in the 1980s, and thus most likely was replaced by the thirtieth issue, More About Thomas the Tank Engine, or the thirty third issue, Thomas and the Twins.
- According to Chapter 15 of The Thomas the Tank Engine Man entitled "Really Useful Engines", Christopher Awdry explains that he submitted the outline for Barry, but the response from the young fans was that they wanted Thomas and his friends, not any more new engines. So he quoted: "But, I haven't altogether given up; you could say Barry is dead but not yet buried!"
- Additionally, it has also been suggested that the publishers demanded to have more Thomas centric books. This was likely compounded by the fact that, at the time, the television series based on the books was running strong and had catapulted Thomas into the spotlight.
