Merddin Emrys is a Double Fairlie locomotive, the third such locomotive built for the Festiniog Railway, the suitability of the type having been proven in tests using Little Wonder. Merddin was built in the Festiniog Railway Company's own workshops at Boston Lodge in 1879 to the design of Percy Spooner and has spent its entire working life on the Festiniog Railway.
Crew figures by Skipper1945.
Thanks to Paul Hobbs for his mesh library elements, some of which have been used in the model and for the great tutorials, which helped me get this model working.
