Travelling the nation and abroad, this third part of the Building a Model Railway series takes the viewer behind the scenes of leading manufacturers, suppliers and model layout builders while presenting the diversity of modelling scales, from palm-sized N-gauge to ride-on 7¼, their pros and cons along with expressions of joy and satisfaction they bring to their constructors’ lives. The production also includes interviews with exhibitors at Scotland’s largest model railway show, tips about how to plan for exhibiting a railway layout, some of the best layouts in the UK along with a behind-the-scenes look at two leading Scottish modelling clubs who offer up the advantages of belonging to a club.
