How to recognise Duncan

Look for Duncan's yellow colour scheme, narrow-gauge well tank engine and visible number 6. The character design is associated with Talyllyn Railway No. 6 Douglas. Faces and small details change between physical models, CGI animation and newer reinterpretations, but the main silhouette and identity remain the most useful clues.

When comparing a toy or an image, check Duncan's name, colour, number and production era together. This character began in the physical-model television era and also appears in later CGI stories. A matching character does not by itself guarantee that two toys use the same track, coupling or scale.
