Ever since the first ever train was used to carry coal from a mine in Shropshire (England, 1600), the technology of railway transportation has never looked back. It has only evolved and developed and remains one of the most important developments in the history of mankind even in today's age. The biggest invention in this field was the development of steam locomotive, but it took another two hundred years for commercial rail travel to practically begin. The railway systems of present day are much more complicated than they earlier used to be. This book will provide readers with an insight into these discussed topics and will prove to be a complete technical guide. It will also present a precise overview on some of the world's most well-known railway systems. The main purpose of this book is to prove beneficial to the learners, practitioners, workers and engineers involved in this field.
