The steam locomotives which served industry spent their working lives mainly behind the walls of factories, docks and shipyards, unseen by most people, and only in the colliery districts and in the iron-ore quarrying areas of the East Midlands were they a familiar sight to the general public. However, there was a fascinating variety of types, produced by numerous makers in many parts of Britain, and fortunately a great many have survived and can be seen on preserved railways. This book gives an insight into the origins and working lives of these little-known steam locomotives.
