Now in case you think I am making this up, here is a YouTube video of the loco in action at Pixieland near Bude, Cornwall, courtesy of Nick Tozer: Pixieland Miniature Railway - 1993. The original machine had a somewhat hazy history, but was eventually sold to Pixieland by the Trago Mills shopping chain. After replacement by an Exmoor Steam Railway 0-4-2T loco 'Dennis', the loco was grounded, eventually being re-united with it's wheels by the Sherwood Forest Railway when it moved there late in 2007. As can be seen, at some point (pre move) the body was rebuilt to a loose 'diesel outline'. The loco is very much in need of an overhaul and is seen here on a rare outing on a passenger service in Nottinghamshire:
Coming next in the series... well, I'll have to find it first...!
