Great little layout and gives me some inspiration to create my own, full of character and atmosphere. What is the concern with the wiring. As I would have thought as long as the gentleman has ventilation, its PAT tested and is inaccessible to touch when operated then it would be fine it appears to be in a plastic case so is insulated. Forgive me only just starting in the model railway world and only living in a small flat I don't have much space.
