Gordon Gravett’s third book is by far the best of the series. It covers the basic ground cover, roads, rivers and details. Mr. Gravett goes into some detail with each area of scene construction. He shows a number of in-process steps and lists the materials used. Some of the materials are unique to England but local sources can be found for many of the items.
Mr. Gravett has produced some of the best looking dirt and mud roads. His technique looks pretty straight forward. It will take some practice to get the techniques down. He shows how to construct puddles using microscope slide covers embedded in the mud. A novel approach but very realistic.
If you are contemplating any scenery work, you should invest in this book and read it. It will help you create a more realistic scene for your railroad.
