The Brave Locomotive is a six-minute independent animated short film produced and directed by Andrew Chesworth with music by Tom Hambleton at Undertone Music. It was conceived as a love letter to the Andrews Sisters and 1940s animation.
Andrew Chesworth developed the concept in 2008, and produced and recorded the music with Tom Hambleton in 2009. The complete animatic was storyboarded by Chesworth. Although the project was shelved in 2011 when Chesworth began as a CG character animator at Disney, it was revived in 2020 during the pandemic with the help of Patreon and completed in 2023.
The work-in-progress of the opening sequence was posted on YouTube and Vimeo in 2015, where it received over 10 million views and helped inspire the project's eventual completion.
