It's probably just a brain fever, but I have this memory of seeing a photo or two of Talyllyn running without her cab in the last year or so, presumably for a photographic special or the like.
Or did I dream it? If anyone can shed any light/point me in the right direction...
P.S. Yes, I know the 'obvious' is to ask the Talyllyn Railway themselves, but the Gnatterboxers are usually just soooo helpful
EDIT: already found this from 2007, but a side or 3/4 view would be much better
