There are a couple of significant and actually, physically, miniature 15" gauge steam railways in the UK. I say a couple because the Ravenglass and Eskdale Railway (Cumbria) and the Romney Hythe and Dymchurch Railway (Kent) are the preeminent ones.
They both served as genuine forms of transport at various points in their histories.
I'm always amazed that the Ffestiniog engines were built just around the corner from where I live at the Hatcham Iron Works on Pomeroy street in New Cross, London. It seems unbelievable that you would setup a locomotive works so near to central London.
