L M S & L N E R Steam Locomotives, is the result of over two decades of photographing steam locomotives in action in many parts of Britain covered by the former LMS and LNER Railway Companies. They were the two largest of the ‘Big Four’ Railway Companies which operated in Britain between 1923 and 1948. The majority of the photographs were taken during the British Railways era between 1948 and 1968. Although the author Malcolm Clegg has a sizeable collection of steam locomotive photographs taken during this period, the photographs which appear in this book are from the private collection of his lifelong friend and family relative, Mr Peter Cookson (a retired school-master), himself a railway historian, author and amateur photographer, who has kindly provided the photographs for publication in this book. Many of the photographs selected are rare and unusual for a variety of reasons which should appeal to railway historians and steam enthusiasts alike.
