In a similar style to our previous OO and N gauge titles in the same series, there is much practical advice, with over 30 pages of step-by-step modelling features (including customising O gauge locomotives, building lineside details and installing digital decoders), together with the construction of an O gauge Setrack project layout. There is also a look at the history of proprietary British O and a gallery of inspirational O gauge layouts from the pages of Railway Modeller through the years. Even larger scales, such as Gauge 1 and 3 are covered in their own chapter. Within the 124 pages (including covers) of this perfect-bound, full-colour book there is plenty for the modeller to read, digest and be inspired.
