Military field railways were primarily used for supply purposes, but also for the transport of troops and wounded. Particularly during World War II, they played a significant role, especially in the East. However, their history also includes peaceful times. To this day, numerous vehicles have survived and continue to delight narrow-gauge enthusiasts across Europe. In this book, Alfred B. Gottwaldt sheds light on all the significant details in the history of these small railways, drawing on a wealth of official documents, authentic photographs, and personal accounts.
