PETER JOHNSON is a well-known and respected historian of narrow gauge and light railways. He has had many articles and books published over the last forty years. This book on the Shropshire & Montgomeryshire Light Railway is the precursor of a new book on the adjoining Tanat Valley Light Railway. This is his ninth book for Pen & Sword Transport for Pen & Sword, mostly on Welsh narrow gauge subjects. His last book, Mail by Rail, was about the Royal Mail’s travelling post offices and the private underground electric railway that connected sorting offices in London. He lives in Leicester, where he continues to research and write books on minor railways and enjoy railway photography.
