Murdoch is an orange large and strong goods engine.
- The number of Murdoch's wheels is reduced due to the size of his model. Other characters who are affected by this are Emily, Gordon, Spencer, Hank, Hiro, Freddie, Connor, Caitlin, Gator, D199 and The Diesel.
- His front buffer beam is lower than usual. Arthur, Hiro and Patchwork Hiro also have this feature.
