Fan Casting Gwyneth the Forest Tank Engine in Falklock Northern Railway Up Close

Gwyneth is described as being a cheeky and fussy little engine. She often gets into scrapes, usually by being over-eager to do things best left to bigger and more sensible engines. But clouds never last long in Gwyneth's life and she is soon bustling about again, playing her part in the yard and on her very own branch line between Guinevere and Twin Falls, of which she is extremely proud. She loves teasing others from time to time, especially bigger engines like Taylor and on occasion brags about her superiority, but is always brought down to Earth in due course by anyone willing to correct her, especially the Iron Director and her two coaches, Zachary and Xavier.
