Whilst the vast majority of new entrants to the hobby of railway modelling select the popular scales of 2mm and 4mm, an increasing number are choosing to go for 7mm or 'O' gauge. In Britain, 'O' gauge equipment is produced at a scale of 1:43, which is 7mm to the foot (using the common British practice of modelling in metric prototypes originally produced using Imperial measurements). It's often called '7mm scale' for this reason. This book will explore all the usual themes for modellers - such as planning, baseboard construction, trackwork, wiring and much more - but will do so from the standpoint of those modelling in 7mm and all the illustrations will feature 7mm scale models. Of particular importance, especially for a scale where the quantity of ready-to-run equipment is limited (but growing), the book will also cover the availability of RTR and kit-built models alongside the possibility of scratch-building. One of the factors behind the popularity of 7mm is the possibility of constructing garden railways, and the book also deals with the possibilities and pitfalls of this type of railway. Fully illustrated throughout this is a must read for anyone considering modelling in this scale.
