- Thomas was originally going to have a larger role in the episode, but his voice actor RightonTracks10 retired from voice acting during scriptwrting.
- This episode will be re-done with SI3D's new model of Daisy in 2016.
- The reason Daisy's RWS model was used is because SI3D's model only had one face, and it would be difficut to add faces by photo-editing as most of the runaway is in video.
- The idea for the story was suggested by DarthWill3.
- Railway Series references include Thomas in Trouble, Old Iron, and Daisy.
- A reference to WTLNetwork's Youtube Poop, "Feeble?!" is made in this video at 9:06.
