Wilbert first appeared in the fifty-seventh episode, Doubts. It was also mentioned that one of his brothers would be coming to help on The Little Western, but will not be coming for a couple of weeks. That engine, Sheffield left his old railway and helped on Duck's branch line with both passengers and goods. In Sheffield's Secret, he appeared from the same Railway Series story where Wilbert met Duck, Oliver and the Scottish twins, telling them about an engine who went cab over wheels at a steelworks factory.
Wilbert is a Hunslet Austerity tank engine, like Sheffield.
