 Children s animation from the  Smallfilms  team of Postgate and Firmin. In the  top, left hand corner of Wales  runs an archaic railway line staffed by such characters as Jones the Steam and Dai Station. Their pride is Ivor, the steam engine with a will of his own and a penchant for such things as looking after dragons in his firebox. Not quite so pervadingly melancholic as some  Smallfilms  creations, however it maintains an enchantingly slow pace without being sickeningly sentimental or patronising.
