This book is a history and global inventory of gauge and scale for toy and model trains without a bias to what I think is the preferred gauge/scale combination. Although this is a worldwide overview it is of course subjective caused by my geographical background. A lot of stocktaking of gauges and scales is present on the internet, especially in tabular format. The present book is more descriptive.
A book with text and pictures on gauge and scale for toy and model trains.
