This is an intriguing N gauge; 1: 148 scale layout by Kevin & Judith Cartwright featuring lots of detail and one of the best transitions from the 3D layout scenery to the 2D backscene that I have seen. It was seen at the Warley Model Railway Exhibition in 2015 and the Southampton MRS Exhibition in 2018.
