- When Nitrogen passed on their sets to Arc, some were missing information needed for production. This meant that some sets had to be completely rebuilt based on pictures to make them look identical to their Nitrogen counterparts. The Sodor Search and Rescue Centre is one of these sets.
- The animation software Arc/Jam Filled uses for Thomas & Friends is Maya.
